My game plan has 4 out of the 6 goal line defenses in it. https://mfn71.myfootballnow.com/gameplanning So it was the games choice to call 3 Deep Zone Under more then the others. But the others were still called and most of the time that run play still worked without warning for using it too much. He ran the same passing play repeatedly as well but that wasn't as effective.

Play overuse penalties are only stated if the outcome of the play is negative for that side. However, they are still being applied.

The bigger problem is that play overuse only impacts a player's technical ability (bonuses applied to non-improvable skills), so unless your players are superior athletes (i.e. have >Speed), you will never "see" the overuse bonus anyway. And, I'm almost certain, it doesn't really matter because of the relative value placed on Speed and some other non-improvable skills.
