Now, let's be fair: in Uncanny 175, which you posted scans from, Scott takes out the entire team singlehandedly, including Storm with powers, and with a couple broken ribs on top of it. Claremont liked Scott, and as much as he was characterized as neurotic and repressed, you wouldn't want anyone else to have your back in the battlefield.

Unfortunately, after the Powers that Be decreed that he leave Maddy for the resurrected Jean, there was no way to sell the plotline except to make Scott an irredeemable bastard, which happens in Uncanny 201. When Storm kicks Scott's ass, Claremont hasn't forgotten that he'd previously demonstrated him to be her equal or better in combat, he was making a point - essentially pissing all over the unrecognizable wreckage of a character that Marvel editorial destroyed.

Of course, the in-story explanation is that Maddy unconsciously used her latent psi powers to throw Scott off his game, but everything about Maddy after Uncanny 200 is so wonderfully meta that the behind-the-scenes story tends to be the more interesting one.
