Maybe they found it performed better, like Adrian Holovaty found for soundslide: http://www.holovaty.com/writing/in-defense-of-canvas/ (see "stacking canvases")

Stacking canvases makes sense when you have ones that either only need to be built on startup or change infrequently. If everything in your animation is moving (like this one) then there’s no performance benefit.

Are you sure about that? Would be interesting to see a performance comparison.
