My native language is Polish too. I wouldn't be 100% sure that this guy is a fake. Polish is indeed a hard language - pronunciation is tricky and there is a lot of conjugation struggle to get through (even names are changing suffixes dependently on context).
What I think happens on the video is that the guy has a list of different phrases/words (prepared for this particular situation) and maybe some pronunciation notes. That's ok, I would do exactly the same. You just cannot memorize all the necessary core words in one hour but you can use them easily if you have a reference material (plus you keep the conversation going and practice more).
He does standard mispronunciations that every non-native Polish speaker does at the beginning. However, you can hear that when the lady replies in Polish, there is nothing to indicate that he actually understood what she said. He gets the questions after she gives him some hints in English. If he was preparing just for an hour for this skype call it is certainly an excellent starting point.

Agreed on that second part. I'm skeptical too but having seen Benny's Youtube videos and knowing that he already speaks a dozen or more languages and that he has reportedly learnt them enough to be conversational in months ... I think he has a handle on how to make specific sounds already and probably knows a lot of cognates.
He's not just a random guy, he appears to be trying very hard; I wouldn't call it fake without further evidence; he clearly has a great talent and many people appear to have had success using his methods (which he passes on for free).
In this TEDx video, https://www.youtube.com/watch?v=HZqUeWshwMs, he says he started learning new languages at 21. He looks mid- to late-30s to me which tends to support his "3 months" claim as being viable as well.
