Let's say a Bounty Hunter is attempting an ambush, making a Stealth check before attacking the PCs. If he gets Advantage, he may toss some Setback dice at the PCs initiative check. A Triumph would let him upgrade the difficulty (from 0 to 1). Depending on the circumstances, it may be better to boost his own dice or penalize his opponents, but either option can work.
As mentioned above I will skip the ambushing Stealth check, merging it with the initiative check, instead:

Don't roll twice, when one suffices.
