To reuse the insect analogy, there might not *be* only one single over-riding 'leader' of the Borg. The queen might just be the queen of one particular collective or another, while all the other 'collectives' of Borg might have other queens. Kind of like, Ants have no single leader, but one hive of Ants might have only one queen, while another hive has got a different queen ant.
The ones on Voyager might reasonably be completely different Borg Queens (despite Alice Krige coming back to play the one in "Endgame").
This still doesn't preclude the possibility of all the individual Borg Queens sharing a single mind within themselves (and each other?).
