Not quite so. It simply means that all actions occur, from our perspective, simultaneously. Thats what would happen to a being outside of ‘time’. He could perform millions of actions, but if you looked at the beginning and the end of God, if that were possible, then you would see the same millions of action in their entirety, all at once, so to speak.
What would be logically impossible, I think, is for God to be only capable of performing one action. Since then you would have the logical impossibility of a before the action and an after the action. Which would violate your idea of a timeless God.
