You'll find that if you get both cups in position and then torque down just the non-drive side that will go fine. There's no reason for the other cup to want to move - especially if it is English.
And that yellow stuff is thread locker.
+1 in my experience. I measure the protrusion of the DS spindle/axle to set up the chainline and use Loctite 242 (blue) in addition to the yellow Campy stuff to seal and prevent galvanic corrosion (fused cups are a *****). that little bit of yellow thread lock does not cover all of the threads. Anti seize will work also but not lock in you cups. Disadvantage of Loctite is you can't re-torque the cup after the cure w/o replacing the Loctite, although you should not need to.
