I think it's good to tell yourself "Don't make it about me" but in the end, he was a leader who had to let go of team members. Seems natural that he would feel things over it. It would be like saying "Startups die all the time. Don't make it about yourself." From what I read (and I don't know this person at all) he seems to really own his role as a leader.
I noticed is that he took responsibility for strategy though, which is refreshing to read every now and then.
The advice was never "Don't make public announcements about yourself" it was "When you're telling the employees they're being laid off, don't talk about yourself". There is a very clear difference there. None of the advice talked about what to do or not do during public announcements.
