It isn't really helpful to think of it as "reflecting common-mode waves

True for a bench circuit. Not necessarily true for a distributed
network. In fact, a choke that makes the outside braid of a
transmission look like an open circuit (best case), makes it look
like a short circuit 1/4WL back from that point. If the choke is
placed at an existing current minimum point, it will have little
effect.
