Rather than allowing the interaction animation to complete. Unlike other pages this will take the animation length to load into memory so it needs to start asap
Tech speak basically right now the code to actually load that page doesn't fire until the tile flipping animation has completed. That's fine for the lighter pages, but for this one it takes a little time to load, so I could let that process start whilst the animation is still playing, making the app feel faster.
A lot more goes into these apps than you might think...
