He means mathematical projections. For example, calculating rotation velocities in a cartesian projection is harder than using cylindrical projection.

Nope you're giving him too much credit. He meant projections as in to a different view on the problem. Not anything more well defined than that. Your manner of explaining it is much better.

I very much meant mathematical projections, but also (by analogy) other kinds of perspective shift where they have enough of the same properties.
