That is correct: the only relevant requirement for Diversity mode is
*frequency* locking between the two separate synthesizers. 

The phase locking is an almost-accidental side effect of fully digital
frequency synthesis. When two identical digital synths are given
identical frequency instructions and forced to march in lockstep by a
shared master clock, they will automatically be both frequency-locked
and phase-locked. But as Vic says, that RF phase lock is of no
consequence for Diversity; the only relevant point is the *frequency*
locking.
