The only step that need occur after the film is removed is a final dunk in a wetting agent, which is easily done in a tray.
Jobo processor instructions read as follows:
"...The final rinse of a process should have at least the first three cycles of rinsing done with the JOBO Lift, even if you are planning to finish the rinse off the processor. This action rinses the JOBO Lift and leaves it prepared for the next process run..."
After those three water rinses in an Expert drum on a CPP2, I remove my film and place it in an Inglis film washer to complete the process. Jobo's procedure is primarily intended to rinse out the Lift. It might remove fixer from film to so-called "commercial" standards, but, in my opinion, shouldn't be relied on if extremely long negative life is a goal.
The only way one can be sure that a particular film washing regime meets one's needs is to perform a residual hypo test at the end. I suggest taking that approach if water is in short supply or, if it's abundant, making ample use of a dedicated film washer to ensure thorough washing.
