So...is the term "extended arm bar" unclear?

I worked a NF game with a ref who would hold up two hands with open palms and fingers spread apart at me when I was giving the ball for a throw in after a substitution. I presumed that was his way of telling me "OK, we now have 10 players in the game, go ahead and start throw-in." Later he told me that two hands up meant "stop/pause", I told him that his mechanic was confusing.

I use that all the time -- and I only work HS basketball.
