wglGetCurrentContext() does not create a context, it merely answers the context that was most recently made current.
Take a peek in sqWin32OpenGL.c in the B3DAcceleratorPlugin source code. It's hiding a lot of tedious stuff; "creating a context" is about a lot more than wrapping a single API call. The B3D plugin nicely abstracts this away so you can use the same setup code across platforms (and can also use Direct 3D as a backend, although Croquet-OpenGL doesn't use this).
