You may be correct (twas a long while ago I'm going back now) but I understood it was to do with overlapping (in space) of replies when they are displayed back on ATC Radar screens as well as the fact that the ground processor would be dealing with co-incident (in time) replies from a single interrogation when the a/c are very close - not that the ADS-B is triggered that way.
Have I mistakenly combined "garbling" with "superimposition" - with the first being a processing issue and the other being a display issue?
TCAS issues does make sense as well!
