It's good to call out hypocrisy when someone is doing something negative which goes against the moral stance they have previously taken.
It's very strange to call out hypocrisy when someone is taking a moral stance against something negative they have previously been guilty of.
The former is an attempt at encouraging someone to think twice about bad behaviour, the latter would be an attempt at encouraging someone to think twice about good behaviour (considering we can't go backwards in time). I guess you could argue that it's an attempt at encouraging good behaviour during some theorhetical future event in line with the current moral stance... but it doesn't seem like a really pressing point to make.
