What is interesting is that if the bill passes with a 2/3 majority Presidents are unlikely to use the Veto. Nothing stops them from vetoing it but they usually take the passing with that strong of a margin as an indication that the veto would be overridden anyway.
That's unlikely, so you're correct in parsing it as a statement being made, not than something that they actually -want- to have happen.
This is extremely common in the US congress.
