This would have to be tested. You can still win post ult, especially if you are able to bring in Mk6 and nuke bomber.
I think that is what he is missing.
With scimitar as the only reinforcement, if they do happen to get to ultimate first, (bomber should be dead) just hit auto and I bet you will still win.
You can also help make sure they have the other sabotage ready by their 2nd turn by using all abilities possible so you are getting TDs. Only time I have not seen opponent use second sabotage on 2nd turn is when I just do basics up to that point and have a few dodges. It is very rare that I am not worried.
