Orion wasn't able to act with his full power as Grand is the thing. Grand servants are summoned by the World, rather than through the grail system or anything like it, meaning that they are much closer to pure spirits with much higher quality vessels. As a tradeoff, they can't actually use that power proactively until the World designates it (in other words, when a Beast manifests for them to fight). Orion was using his normal skills as the top-level Archer plus his own blessing of Poseidon to break down Caenis' (that's why the last fight against her involves using him to wear down her blessing). The only time we got to see his actual power as Grand Archer was when he shot down Artemis, and because she wasn't a Beast, he shed his Grand title to do so.

Poseidon's Authority is strong, but it was being in the sea of Atlantis that let it take effect. Anastasia or Surtr-Sigurd would've been able to supercede that with the greater amount of native Authority they had in their own lostbelts.
