Well it could be that you've reached a certain age and aren't confident that you'll be an attractive hire to anyone else.
It's just an anecdote but I remember chatting to someone who worked for Microsoft in Ireland and was going through a performance review / PIP like process. He was in his early fifties and said that it inevitably seemed to happen to people once they reached a certain age / salary point.
Age discrimination in hiring and retention is a real thing. This seems like a systematic way to cover over it to make it look like something else. Smarmy, at best.
