In the sense of "there is no progress, author has decided to have Asuna take a back seat and spotlight Kirito's relationships with other girls instead" - he even apologizes for this himself
. It may not be a reset, strictly speaking, but the effect is kind of like a reset. Like an omnibus adaptation of a VN, "girl of the week" format. And yes, it does not change the fact that Kirito/Asuna are the one true pairing of SAO - I'm not out to dispute that (nor do I care, though they make a good couple as far as I'm concerned).
