Comment (by teor):

 I think recent versions of stem use fallbacks by default for descriptor
 fetches.

 Anyway, here is the authority behaviour:
 Authorities cache any descriptors posted to them by relays
 Authorities try to fetch all descriptors for every vote and consensus they
 successfully download and validate.
 Authorities cache all descriptors they have ever successfully downloaded.
 Authorities remove a descriptor from their cache when it expires, or for
 miscordescs, when it hasn't been mentioned in a recent consensus.

 So the number of descriptors returned by an authority depends on its
 reachability and uptime.
