Boreas had never fought a Demon King before, and their abilities were a mystery to him, he should have been contacting the God King at this time but all communication was being blocked by the black field surrounding the vault.
This meant that Ohrox must have realized that if he broke out from the vault then he would lose, and normally Boreas should have turned his attention towards breaking free and alerting the rest of the gods.
Yet the pride of a God of Trion was unmatched, as a High god of Trion, by all means, he should be able to battle a Demon King, and if he fled from his vault to beg his siblings for aid, he would never be able to raise his head high in the presence ever again.
Also if the detail of how the Demon King had deceived him and played him for a fool at the beginning of their battle left the vault, the God King might even kill him in fury. Golgoth was a cold bastard, but he did not suffer fools.
