I dont't know what that measurement is supposed to show.
If the point is that it's not showing 2.5", it's not supposed to.
The 2.5" is the inside diameter of the PIPE that the fitting
mates with. It's not the inside diameter of the fitting which
is going to be a lot larger. The real question is if it fits
snuggly when it's put on, which I hope it does.

He cut it flush with the valve because the coupling is going
OVER the jandy valve. He doesn't want any pipe left outside
the valve. It was either go over it, or get the special tool to
bore out the pipe already glued inside the valve.

I don't see why there should be a lot of play in this. If that
Jandy valve is designed to work with 2.5" fittings, then a 2.5"
fitting should fit over it just like any PVC pipe connection.
If it doesn't and there is a lot of play, then glue isn't the
answer. You might get away with it, but that joint will not
be nearly as strong as it's supposed to be.
