Well, first of all the quality is good enough :-)
It isn't hard to prove lip syncing when 1) you compare recordings from different days in a multitrack session in let's say Adobe Audition and as a result vocals are 100% identical. 2) you can clearly hear pitch-correction.
I know sometimes people wrongly acuse Ayu of lip syncing. But it's not the case here, since I've got evidence, so it's evident for me.
Of course you're free to believe what you want, but for me Ayu lip syncing several songs is a fact.
