There’s this claim I see here of people that say that while running slow they heelstrike and then the more their speed increases the more they strike forefoot. How can this be? It’s a total different thing these two strike pattern.

...and, when I sprint, I land on my forefoot. How weird is that?
You sprint on your forefoot and jog on your heel- that’s very weird

We don't jog here. We do "aerobic runs" and "workouts".
:-)
For better or worse I have a Stryd running power meter. Not sure what I think of running with power overall, but it gives accurate distance when I run on treadmills. A side benefit of the device is that it gives information on running dynamics. From that info I know that as I run faster, I waste less energy, remain in contact with the ground for a shorter time on each step, have less vertical oscillation and more leg spring stiffness. I can't tell whether my footstrike changes or not but all the other indications are positive.

Because they are doing two different things so of course things will be different. You a moran, son?
No. They’re doing one thing- running. As a forefooter, my foot always strikes forefoot- sprinting or jogging
Toni Nett did a film analysis of this several decades back.
"1. All runners, regardless of event, initially plant the foot at the outside edge.
"2. 100m and 200m runners initially contact high on the ball of the foot, including the joints of the little toe (Figure 1 above). 400m runners contact slightly further back from the sprinters. Nett calls this the 'active or dynamic ball plant.'
"3. 800m runners typically land along the length of the 5th metatarsal, with the heels and toes slightly off the ground at contact (Figure 2 above). Nett calls this the 'metatarsal plant.'
"4. 1500m runners land in a manner similar to either the 800m runners or in a manner similar to marathon runners – in other words, this is something of a transitional distance (Figure 2 or 3 above).
"5. Runners in events ranging from 1500m to the marathon contact 'with the outside edge of the arch between the heel and metatarsus (Figure 3 above).' Emil Zatopek was included in this group. Nett calls this the 'passive or static heel-metatarsus plant.' He found only one exception to this [among elite runners]– one runner landed on the ball .
"6. After contact, the heel touched down in all runners filmed, even sprinters."

Get off the computer and without forcing or thinking about footstrike do the following:
1. Jog 8 min pace and you should land more heel first
2. Sprint for a hundred meters and you should land more Forefoot
The faster you run the more your leg rotates and more your foot rotates as it lands.

Your pace is probably the same for both. People who transition across their foot according to pace have better range than you.
I really want to see someone going nowhere fast with a 180 cadence hammering out 12 minute miles. It would be a pure joy to see. Oh, the efficiency.
Forefoot strike is the result of a relaxed ankle and foot while in the swing phase. heelstrike is a result of a dorsiflexed foot and a stiffened foot before initial contact- a runner doesn’t change these patterns between paces. Maybe only sprinters dorsiflex their toes and stiffens their feet while sprinting, but they still strike forefoot. A heelstriker stiffens his ankle and foot at all paces and hit heel first due to lack of relaxation in that joint

This.
For me, my footstrike does not change at all with speed. I land on my forefoot, whether I'm jogging, running, spring or walking. At very low speeds, you might say that I have the form and grace of a ballerina.

IMO it's almost quadratic. When I am easy jogging i.e. if between intervals, I forefoot strike. It's too awkwardly slow and I get oddly bouncy. Heel striking at a slow pace just feels like I am intentionally smashing my heel into the ground. More normal aerobic run then switch to heel, naturally.
foot contact patterns, when done correctly and efficiently, are velocity dependent.
sprinting is also a skill. some distance runners "can't or don't" sprint. they just "run as fast as they can" with the same mechanics as their jogs or workouts.
