The weird thing about that moment is that the intention was that you can see the Predator's true for through the reflection in the puddle in the alley. Like that water negated the light-bending effect of the cloak, but the Predator fades into view when the camera tilts down (it also dissolves between two different Predator shots, one where he's standing and a second where he's easing into a crouch), which gives the impression that the cloak is just turning off, only to be working again in the next shot. It's a neat idea, and definitely one they should bring back now that it's easier to do the cloak effect, but it's just weirdly executed in the film.
