I believe that in that situation, there was no violation, and it's acceptable to play that way (and I still think so).

That's the problem – you still think that way. It's okay to miss the nuances of the wording when analyzing it yourself; it happens to everyone. But after it was pointed out directly...

I also said that in a controversial situation, it will always be interpreted in favor of the player, and there's nothing to punish for.

That reasoning is correct. But you were motivated by different reasoning. The fact that their answers coincided is just luck; they could have easily been different. Plus, your incorrect reasoning didn't allow you to convince Gomunguls of your rightness, and he brought the episode to the attention of everyone.
