I don't think there is any reasonable utility function that is consistent with the actions the AI is claiming to have done. There may be utility functions that are consistent with those actions, but an AI exhibiting one of those utility functions could not be an AI that I would consider effectively omnipotent.

There is no connection between the intelligence or power of an agent and its values other than its intelligence functioning as an upper bound on the complexity of its values. An omnipotent actor can have just as stupid values as everyone else. An omnipotent AI could have have a positive utility for annoying you with stupid and redundant tests as many times as possible, either as part of a really stupid utility function that it somehow ended up with on accident, or a non-stupid (if there even is such a thing) utility function that just looks like nonsense to humans.
