Pahoo doesn't speak, so the only way he and Yancy communicate is by sign language. In this, and other episodes, the one signing is behind, or enough to the side of the other one, that he wouldn't be able to see the signs. But that person responds or acts on what was signed.
The two of them are so familiar with each other that each knows instinctively what the other wants. Examples being Yancy knowing Pahoo is behind the bad guy and the way they pass each other Bowie knives.
