Yes, he may act freely while under the PfE. The problem is that the PfE is generally much shorter than the domination. 
The person is otherwise free to act but must carry out the last command. He will not do anything self-destructive, but receiving a PfE is not self-destructive and your friends will not suddenly be considered your enemies (unless you were directed to attack them), so you will not purposefully resist their spells. However, if you were directed to attack your comrades, I'd say you treat any spell by them as hostile and do your best to resist or thwart them.
At that point, it really boils down into a judgment call, though, so I could see someone arguing against that idea. The judgment of course being how powerful you think the domination should be and how you rule "ally" vs. "enemy", etc. For example, if you are dominated into attacking your allies and the cleric in the party casts a mass heal, do you gain the benefits if the cleric targets you as well? I say no. If you also say no, then the PfE could be resisted as well.
