I think the point is that when a decent 10k/marathon guy tries an ultra, he often wins (by a LOT). But well known ultra-runners routinely get waxed by good weekend warriors at the local 10k.
Very average runners can finish top 10 in most ultras, but many top-10 ultra finishers can't compete at any conventional distance.
I don't think your first statement happens as often as you think and when it does it is often at a less competitive ultra.
Your second statement is somewhat skewed by the sheer numbers. There is only a tiny fraction as many ultra runners as conventional distance runners. Top ten in a 200 person ultra should be compared to top 100 in a 1000 finisher conventional 10k/marathon.
Perhaps even more important is what are your definitions of decent and average? By LRC standards 33/2:30 might be considered decent despite the fact that those times can only be achieved by maybe 5% of the population
