Not different, as we have class E too. I work in class C, and we often have VFRs flying same altitude via same waypoints. I wouldn't sit happily watching as they approach same point same time same altitude even though legally I can. That's all. Of course one could argue in lon run we'll all be dead.
So yes, legally it's fine, also it might have happened he only learned about the vfr traffic when it was too late to actually do something constructive. Otherwise, I would find it strange.
