Quite a different situation I think. CP3 and Quin didn't have a long history together. So the hug is really lacking much meaning.
Favs and Hayward on the other hand has a long history together. So for Hayward to 'draw out' that 'memory' at a time like this (i.e., merely months before Free Agency), that's HUGE. Why? Because to draw out that memory and then in 2-3 months turn around and sign with the Celtics is effectively saying '**** you' to that said memory. And that's just cruel. And Hayward by all account is not a cruel man.
It would be like you broke up with your Ex, and after 6 months just as you've gotten over her she comes around to your house and say she needed you. Then the next morning she walks out on you again leaving without saying goodbye. That would also be cruel.
