No, I don't think so. It was a kind of non-conversation that way; Nathan was trying to pin Mateusz down to holding certain views that Mateusz plainly said are not any kind views expressed by the game but rather one that players may read into the game for themselves, and making the common mistake of thinking that the trailer represents the whole of the image of the game.
Mateusz was right to refuse to offer any interpretation, both because he clearly stated the vision of the game is not to impose interpretations other than those the player creates for himself, and because any interpretation he offered would end up treated as either some kind of political statement or some kind of massive spoiler.
Nathan may as well have asked what Mona Lisa was smiling about. Because he'll get no more answer than he got, nor will anybody else.
"...even a dead animal preserves more powers of intuition than some human beings with their stubborn rationality.... Imagination, inspiration, and longing all lead people to sense that these other levels also play a part in understanding."
