Hi, I don't think it's at all pointless to advise he see a doctor.
Although, RLS can affect the arms, it isn't called Restless LEGs for no reason.
You're assuming that he does have RLS, when actually, from what you say, it doesn't appear he has as the description of his symptoms doesn't fit the diagnostic criteria.
I'd say he needs to see a doctor to find out what his problem really is.
It's not unknown for RLS to present only in the arms but it is rare. It sounds like he might benefit from seeing a general sleep doctor (though they can be pretty useless when it comes to treating rls). The diagnostic criteria for rls are: Strong urge to move - often presenting at the onset of sleep; an unpleasant sensation often described as a creepy crawley feeling - but also by some as pain, electric shocks or similar; symptoms are worse when resting or inactive and particularly when lying down; symptoms improve with movement of the afflicted parts; symptoms are not accounted for by reference to another condition such as cramp, arthritis, positional discomfort or arthritis.
