Ok, I see your point. I still think it's really annoying that we have to do it to get more speed when it wasn't the case in Skate 3.
Wait, get more speed? As in, get more speed to ur spins?? Annoying yes, but it's just a simple half turn. Plus, it makes sense that ur skater would need to prewind their body like that in order to get more spins into ur trick. It's honestly a really easy requirement if u do it properly. Plus, to be fair, this isn't Skate 3. Maybe they have a different mechanic in mind for later, but I'd keep it as is honestly.
