Imo, this is even better. Not only does it confirm how Saitama's power works, but it also confirms that Garou was indeed on par with Saitama anyways, which is pretty much even with Garou being able to make him bleed.
Most importantly though, with these last few chapters, any argument that Saitama solos fiction or whatnot has been completely, undeniably debunked. It's not even worth discussion anymore. Because of that, a large amount of the Saitama wanker fanboys will finally quiet down. That's a win, in my book.
