Office is a Per Device license (assuming you are not using O365 or OEM*) and on the server is licensed per accessing device. So if only one person is using it you license their desktop/laptop with Office 2013 and they can have access to the one on the server (you don't actuall have to install it) / You do not have to license the copy on the server.
The fact it is a service account is irrelvent in this scenario, aside from service accounts tend to be shared accounts so make sure the rules above apply/
*O365 is Per User - each user can install on up to 5 devices., OEM is not allowed in a terminal services environment
