Technical Foul ???

Sure, the activity could be considered fighting. It is likely a situation where the crew discusses to determine if an upgrade is warranted based on what was, or was not, observed by each official.

The subsequent foul by A2 with the elbow is thus an intentional technical foul and the foul by B2 shoving A2 is also an intentional technical foul.

If that were true, it would pretty much be impossible to have a double foul at most points of the game as one almost always happens before the other, even if just slightly.

The rules makers cover this by defining double fouls as "approximately" the same time where the expected result is that the 2nd is considered to still be in a live ball if it happens so close in time.
