There is no plot of the residual distortion sine wave, the sine wave plots are all high level. So, you cannot tell from these whether or not there is zero crossing distortion.
Does Topping itself call this amp Class B or is that just Amir saying it?

Figures 8 and 9 are what I am talking about. Amir doesn't show anything like this, so it is not possible to tell otherwise. Please note that the high level sine waves look perfect in Figures 8 and 9 in both AB and A mode. Only the residual distortion plot tells the story.
So, until I see a measurement like that, I don't accept that this amp is free from zero crossing distortion, despite the very low overall distortion.
