I always saw the usage as denoting intent without forcing an action. It's kind of like putting an action on the stack, to borrow the term from Magic: The Gathering.
Action: Warren would attempt to trip his opponent.
Reaction: His opponent blah blah blahs, result occurs.
It's basically saying "this is what will happen unless something else stops it." Admittedly, I'm viewing this through the lens of the Grindstone, where this sort of thing happens fairly regularly.
