This ability causes the unit to pretty much warp forward to the target, and stop.
But if as you activate the ability, right before the unit moves, you right-click move to a different location, the unit just keeps moving and doesn't stop for awhile, when it does, it tends to get stuck in bad places.
Spoiler:
This one creates a fake unit, and moves the actual unit using the ability right in front of the target unit, but if you right-click move right as you use the ability, the casting unit warps right to the middle of the map instead of in front of the target unit.
