Since the receiver's signal path splits off into separate paths for each, this could help pin down where to look first if it works on one and not the other. A weak receiver is too much like telling your mechanic "My car won't start" without checking to see if the dashboard lights up, or if there is a any sound when you turn the key all the way to "start".
Too many possibilities until the mechanic can start checking off the parts of the engine that do work, to pin down the part of it that isn't working.
The answer to the "AM or sideband or both" question points to the next place that gets checked.
