Good, thank-you! I wasn't aware of that, but I'm not an EE and that's why I've asked to ask one: this kind of things are much better handled by experts in the field. But anyway I have the strong feeling that that wasn't the meaning the person who described transformers had in is head:

That's about windings, and of course in the primary of a 3 phase transformer you'll generally (/there are exceptions.../) have 3 windings, but those 3 windings together make up the primary side of the transformer. The definition of primary v.s. secondary is about which is the exciting part and
