Maybe the MSF curriculum is taught with varying emphasis at different places. When I took the course, countersteering was the first technique they taught us after starting and braking. I practice it every morning in the "S" turn that greets me at my workplace.
As far as the second video goes, I agree that he seems to have had a poor line going into the curve (too much to the inside at the start), and that he didn't have the conviction to lean and/or countersteer the bike enough to match the speed. I'll add, though, that he also braked in the middle of the turn, which is a sure way to lose traction at a speed like that.
On day 2 of the MSF course, one of the instructors braked while turning a bike at low speed, which caused it to drop and fling him ass over head across the bars, accidentally demonstrating the point made in the classroom that braking while turning is dangerous.
