The manga versions are written by that manga illustrator, yes. For example, Kawahara Reki has absolutely no say in what Nakamura Tamako (the Sword Art Online manga's artist), unless Nakamura-san goes to Kawahara-sensei for clarification--and even then, it's only advice and not "must do this".

The manga is the mangaka's view on the series, even if it is an adaption. If this regards 16.5, then it is safe to say that the mangaka supports that Kirito and Asuna did the deed.
