Is this a case of widening and compression? (Dream Evil - Book of heavy metal)

At 0:43, as the chorus comes in:

To my ears it sounds like the mix becomes wider and the compression gets turned up to 11 but any suggestions welcomed

I just heard parts out in the edges to give that momentary zing!!
But I will admit that I was also kinda shaking my head at yet another band trying to do a Judas Priest parody. That said, this is better than many, once you accept how faux it all feels.
Actually, yes I think they do meddle with the levels too. There are several changes one after another. Contrived but effective in this situation.

Yeah, just seemed like higher freqs panned out far all the sudden. Not a bad production move.
