Not if you see what David Davis has stated about the bill
To me it looks like giving the rest of Parliament the opportunity to own the disaster of a no-deal Brexit.
If Parliament rejects the deal, then there is a no-deal Brexit. So Davis can blame Parliament for denying the British People the opportunity of the Fantastic (TM) deal that he brokered.
If it accepts his deal, then that shows that he had the backing of Parliament.
That's Davis' version, no guarantee parliament will see things the same way, not mention that as May and co. are clearly on the ropes more concessions are likely.
