Did Paulie Malignaggi's Lost To Amir Khan Change His Stance On Steroid/Pacman/Roach?

We all know Paulie has been vocal about accusing Manny of PED, which pretty much insulted not only Manny but Roach/Ariza. Paulie also went on to have some words for Khan as well. Khan said he was going to make Paulie pay for what he said about his training partner, head trainer, and strength and conditioning coach. After the fight was called off, Paulie walked up to Khan and congratulated him with a smile on his face. Paulie and Khan showed good sportsmanship and embraced each other with kind words. But Paulie also walked up to Alex Ariza and said something to him with a smile on his face. Alex Ariza had a plain look on his face and didn't say anything in return, but looked like Alex Ariza acknowledged him with a head nod. Then Paulie walked up to Freddie Roach and said something to him with a smile on his face. Freddie Roach had a smile on his face as well and said something in return. I don't know what Paulie exactly said, but judging by his facial expression, body language, and his post fight interview. I think it's safe to say he probably embraced them and had kind words for them. My thing is this I don't care if I lost to a fighter, if I believe the fighter's head trainer and strength and conditioning coach is supplying fighters with PED, why would you embraced them? Even if one of his fighters dominated you, why would you embrace a cheater? Paulie could have just congratulated Khan and did the post fight interview and moved on. Did Paulie have a change of heart?
