Maybe that what's happened. Or maybe this person forgot to mention some details about something else they did at that day, due to a random lapse of memory without doubt. The point is we have no way to know, based on the words of one, very non-disinterested, side.

And, as I pointed out in my original comment, google has massive information asymmetry here.

They have video and email and message history and badge access times and maybe audio recording and maybe more, who knows.

So far we only have this one person's recollection of the events, where he has a huge bias towards trying to minimize his involvement.
