Bashur long left. Personally there are many treaties that countries have signed that conflict. ICC is one of them. The respect of sovereignty of another nation is a treaty far more important than any other. It is the reason Bashir or anyone else can today attend UN meeting in New York without as much as whimper from DC.
Yes he might have already left. Either way, the AU club simply cannot enforce such laws against fellow big men. Still I think he would be promptly arrested, no questions asked, if he set foot in New York. And they might not even hand him over to ICC.
Pundit's claim in red is a funny one. As along as the ICC wants him, Bashir is one president who won't be seeing much of New York, even during the times when all his fellow national leaders are there.
As it is, this matter has already been put to the test. In Sep 2013, Bashir applied for a visa to attend the UN General Assembly meeting. Washington was not amused, but Bashir himself apparently was:
But Bashir at a press conference on Sunday night challenged the US to deny him entry or arrest him adding that his flight and lodging plans for New York have already been made.

(He did not fit the "exceptions" that would have allowed the US to do otherwise.)
A few days after Bashir's public display of African Big-Man bravado, his Foreign Minister had this to say to the UN:
It is with deep regret that I inform you of the refusal of the authorities of the United States, the host government, to give an entry visa to President Bashir and his delegation
http://english.alarabiya.net/en/News/africa/2013/09/28/So, why wasn't there a huge diplomatic flap over that? Wapi African Union or anybody to complain? Well, his Foreign Minister took some liberties with the truth. Bashir himself changed his mind in light of the "offer" he was given: Stay at home, or insist on travelling to the New York with the US government stating that it was "unable to guarantee that he will not be arrested".
How's that for a whimper?
