He's not filming with the others because:

1. He's dead.

2. He's not with the others.

Consider that they have, on more than one occasion, had one character separated from the rest, and so had to film them separately. Neal was seperated from the group from the time he was shot at the end of season 2 until he was rescued in the middle of 3A. During that time, everyone on the show thought he was dead. They could go that way with Robin, and in an effort to keep at least a little suspense until the end of the season, they are filming his "post death" scenes behind closed doors on a set (likely in LA).

I'm not saying that he's not dead, as I do give that option a possibility of being true. I'm just saying that there all options should be considered until we see more evidence. And remember, if we don't see a body, death may be an illusion. (sometimes even seeing a body is suspect, but that is a different retcon altogether).
