Of course. When a switch hears a frame that is destined for a station

Yes, but this is not a very common situation any longer. What you
describe is what a bridge would see, when there are repeaters (hubs)
connected to one of its LANs. These days, each LAN tends to have only
one host connected to it, and the other end of the line is the switch
port. I don't see a lot of opportunity for a switch to detect non-
traversing frames. (?)
