It's too late for 'damage limitation' for either Soros, or Obumba. He could be distancing himself to avoid public backlash when truth about Obumba becomes public, or to help Obumba when truth about himself becomes public.
My bet is that he's protecting himself, or believes he is.
Soros is a psychopath. In his own little world of self, he believes that he is untouchable. That belief is probably reinforced through the many dirty deeds he has gotten away with in the past.
I can't wait to see this guys little world come crashing down.
