Domain Admin User Account

Domain Admin User Account

We are in the beginning stages of setting up Patch Manager Plus for our domain environment. We are setting up a distribution server to download all updates centrally too and are being told that we need to have a user setup on the domain with "Domain Admin" privileges. I'm trying to wrap my head around why that is required when we can simply provide the user with "administrator" privileges on each of the devices it is applying patches too. 

Has anyone gotten around this or can provide some clarity to this setup? Thanks.
