Yes. However, currently the fp heuristic is applied only once to
the root node, so only one solution can be found in this way.

I'd like to say that the idea is to call, if necessary, all primal
heuristics directly from the callback routine that would eliminate the
issue, but unfortunately the fp heuristic is still not available on api
level.
