I think it was a very easy call judging by what the cue ball did. This is a very common situation where two object balls are close together and you can make the shot by hitting either one first.It was a tough call, ...
If you hit the 4 ball first, the cue ball goes towards the 9 (by the 90-degree rule) and stops quickly a little to the right of the shot line. The 9 will not move much.
If you hit the 9 ball first, the cue ball goes immediately into the 4 (by the 90-degree rule) and then scoots off to the left. The 9 ball will move to the right quite a bit.
In either case the 4 goes into the pocket, because the cue ball will hit the 4 in very nearly the same place.
This kind of call is generally easy and obvious and does not need a replay. It is impossible to actually see the two hits live because they occur within a few thousandths of a second. Humans have trouble with anything faster than 100 thousandths -- a tenth of a second.
