People that ride over 100% for an hour simply have their FTP set too low which is not uncommon as FTP is not constant over time.
I think the point that was being made is that the 1 hour point is not in the definition and some genetic freak might be able to do it. But I agree it is very unlikely because if FTP>1hr, then the part between 1hr and FTP TTE is not that steep.
This article explains how you could define FTP:

It is the point on the power curve when power suddenly starts to drop much faster, after it drops slowly from say 20min onwards.
