The subnet manager can give an APM result that will switch between ports on the same node, APM handles both switching to a different path with the same end ports, and also switching to a new path using the same end ports. An implementation supporting APM must be ready for both situations - realistically no additional app code is required to support the multiport case since it falls out for free. You'd actually have to actively work to prevent it... This is why in the IB verbs architecture nearly everything is tied to a *device*, not a port.
