You have to be careful with the 10 kHz output. The output is only updated once per second (the 10,000 pulses in the 1 second period are equally spaced), so you still need the same filter as if you were using the 1 PPS output. I am not sure what the 10kHz output was intended to, but it's not that great of an advantage for phase locking a XO.
The only advantage I could see is if you are using a Jupiter to discipline a very lousy crystal oscillator, you could speed-up the lock by using a faster filter, then switch to a slower filter once lock is achieved. However, even though you will achieve lock faster, the precision will not be better (probably worse) than if you had a good OCXO to start with.
