Sorry for the late reply, but there was a problem with the mailing list.

Proportional means exactly that: The probability will be what you give, up
to an overall constant, which is unimportant since the total number of edges
is always fixed.

To force the edges to always be inside the groups, you should set the
probability to zero, whenever r != s.
