She meant that the Borg don't steal genetic material and grow them into new Borg on the spot like what happened with "One". That doesn't exclude them from reproducing via sexual intercourse. Making a baby borg through reproduction isn't the same as how One came into being. She never said "The Borg ONLY assimilate".
Seven was the first ASSIMILATED Drone to regain her individuality (The Queen would've been more surprised/impressed at someone who was forcibly changed and then broke free, than some lifelong drone who was separated), Hugh was not an assimilated drone in the first place and not comparable to Seven. It doesn't excuse the drones from "Unity" but it's easy to assume that since they never tried to go back to the Borg like Seven did, that the Queen simply didn't know about their survival.
They didn't drop an anvil on our heads over the situation, yes. That doesn't make them horrible writers. The just figured we'd know that Picard was never a drone, and the Hugh was never assimilated.
In this case, Occam's Razor is simply wrong.
