The opponent might have used very wrong orders. It might also be one of those rare, occasional wins. You might lose in the second leg using the same tactics.
I had a quick look at the possible effectiveness of this set of tactics against 4-1-4-1. Some required elements are there, but it looks more like 50-50 (or even less to your side) rather than a proper counter.
Report back after the second match has been played.
