If the profile intersects the revolve axis, the revolve command cuts the profile by the axis and picks the largest piece to actually revolve.

That's to help avoid making a messy self-intersecting surface result (where the surface crosses through itself) in cases where you might have drawn the profile curve with a little bit sticking past the revolve axis.
