Main service disconnect at exterior pole

I’ve asked this before, but I couldn’t find it anywhere here. Regardless…
When a main service disconnect/panel is at an exterior pole(which I see a lot), the remote distribution panels, fed from this panel, inside the house. exterior buildings. etc. would be considered “detached buildings,” correct? The house today was built in 2004 and all feeds from the main service disconnect at the exterior pole were 3-wire. So 3 wire feeds would be o.k., as long as there are no other metallic connections from the pole?

Hope this makes some sense - lol.

For 2004 you would be correct, the change came to eliminate this exception in the 2008 NEC. This is some explanatory material from 250.32(A) in the 2005 NECH:
