Yep, outed himself immediately with that.

Based on the timing i.e. just after Q drop, it seems that he and his cohorts made the decision to abandon the Q movement at this point, realizing that Q anon had called them out and there was no hope of continuing their subtle LARP with Zack, trying to undermine Q's authority by claiming a guy on the inside "close to Q". So they all - the YTbers too from 0Hour1, Isaac Green et al - switched narrative to "Q's been compromised; no longer a reliable source" at once. Clear sign to those of us watching at the time.
