Since a rotation always takes place in a 2-dimensional plane,
With a four-dimensional object you can apply two rotations at the same time and they're completely independent of each other. The maths is actually easier.

I'm going to take your word for it.
But why? Can't a vector be a rotation in space - of what ever dimension you decide? something something matrices something vector something -- Mum! - what's a tensor transform?
