Why do people do workouts of sets of intervals, like 3x4x400 instead of just 10-12x400? What is the purpose of having sets, as opposed to doing the same rest between all the reps? Is there an added benefit?

I am also curious about this. I assume breaks between sets help to have short rests between reps, making it more race specific. But this is all my own conjecture, it would be nice if someone who actually knows what they are talking about would confirm this.
Simple...It's to allow you to complete a high volume session at a higher intensity. I would use it as a way to progress training.
Using your example of 10x400m say at 1500m pace off a minute recovery. If you find you can't maintain your target race pace for that session then break it into sets, say 2 sets of 5 with sufficient recovery between sets to maintain the target pace. Then you progress by decreasing the recovery between sets until you can manage the reps all in one set.
Ok thanks that seems to make sense.
