Hi,
The policy hit-count shouws the number of hits to that policy.
A policy would be hit only for the fisrt path when the session is being created. If the packets match an existing session on the SRX, the policy would nto be hit.
Thus, you can say that the policy hit-count shows the number of sessions created through that policy.
Some more details in the following link :-
