The only thing rusing you is that fucking hideous attempt at a solution. It's not wrong, but I'd rather insert a paperclip in my urethra than read that fuckfest.

The point is diagonally inwards a little bit from B, on the top. If you want a loosey-goosey "intuitive" reason why this is harder to get to, it's because you can move more efficiently to B than the better point.
Going straight to B, you always go up at a perfect angle, like a spiral staircase; you make progress equally in two directions at the same time the entire way there. But if you move the point into the top a little bit, then you can't cheat all the way up; some of your movement has to be inefficient, and for a bit, this overpowers the fact that you're moving it "closer" in space.

I wonder if this problem would trick less people if it were flipped on its side.
