I would have have thought that MMW scanners would be present at those those particular terminals of those 2 airports?
The hand swab station in the PreCheck line here in SAT, at least in Terminal B, is actually before the ID check. When it's open they seem to swab about every third person. There may be some randomizer I've missed but you haven't passed any detector at that point. I "won" the whole lotto a couple of months ago where I got the hand swab and then the beep for a bag search.
