I wouldn't take this as a sincere gesture. So many people say this in the public eye just to save face without any intention to take it further.

I realise I'm replying in context of Sir_Cmpwn specifically (and I have had my own interaction with him in the past on unrelated projects in very sour taste) but it is more common with anybody that promotes an apologetic-but-contact-me attitude. It's an all to familiar trait of people trying to sound good in threads of their topic.
