Are you just looking at the control points of the curves?

Some of those curves just happen to be drawn with a different number of control points in them.

There is no restriction for surfacing commands like Loft, Sweep, or Network that each profile curve needs to have the exact same number of control points in it. It is allowed to use curves that have completely different numbers of points in them.

MoI goes through some steps to automatically synchronize curves like that up to one another when constructing the surface.
