if you watch him closely instead of where it's 553 on the tab he looks like he's using his pinky so it becomes 55x8. So something like this

--------------------------------------
-------------------------------------
-5-55555-----5-55555----------
-5-55555-----5-55555----------
-------------------------------------
-5-55555-----8-88888----------

He uses his thumb for the 5's on the E and his pinky for the 8's on the E.

The next part he's ascending with one shape but it differs from the tab and I'm not able to figure it out.

Thank you very much Naptime (:

Anyone have any idea what chord shape he might be playing?
