... if the rate of the water leaving the hose in both conditions is the same ...
I don't think that will be the case: air-resistance is trivial compared to water-resistance,
which will reduce flow from the hose, and consequently less reaction force.
There's also hydro-static force reducing flow from the hose,
( the deeper the hose is held underwater the greater that will be).
