No, only 1 (effective) license is used, shared by both sessions.

Floating licenses are accounted in some strange way. We have "400"
floating licenses. An interactive session from sgi IRIX uses "10"
licenses, a similar session from Linux uses only "6" licenses. I don't
know if the accounting scheme has any sensible basis or is an arbitrary
scheme thought up during someones coffee break.
