Yep. It's not a matter of whether or not Saitama did or didn't -- it's that we HAVE to assume that Saitama either "playfully" stomped Rover or put zero effort behind his attack, because otherwise, the entire manga/anime is null/void/meaningless. Saitama's character is based around the fact that he can kill monster in one punch (depending on the seriousness of the intent behind it), so if there's actually a monster that can survive an intended attack, Saitama's character is another average OP'd guy instead of a satire against other OP'd heroes/villains.

But then of course, in the manga/anime Saitama is shown to jokingly punch guys into the air without killing them, so it's the same principle here.
