I could buy that it's "cover" for Flake, maybe.
But why does he need cover? What leverage exists over him that would be defused by this measure, but not immediately reapplied if the scenario plays out as you suggest?
He doesn't need cover in electoral terms. It's obvious that the cabal still has some kind of leverage over him.
And if the FBI says "nope," those who control him would still expect him to throw a further tantrum and suggest that the process is inadequate (as the Dems will in any event).
