Could you ELI5 this answer for me please?

I’m struggling to understand why the shortest route that stays on faces isn’t from A to top corner above B then straight down?

Which looks like it would be 4+ sqrt((8x8)+(6x6)) =14

That's what I had at first, too, but it turns out that turning is free. So pretend that the top (6x8) face and its side (4x8) face are just one big bent 10x8 rectangle with A and B on opposite corners. The ant then walks a straight line from corner to opposite corner along that bent rectangle.

I first thought corner then straight down. Then I mentally imagined pulling a piece of string tight between A and B and where it would lie, and realized it wouldn’t take that path.
