That is the way I was thinking it worked but then got talking to my beek friend (he's still pretty green too) and he got me really confused, which is getting easier to do as I get older :-D
One last question for now.... is there ever a time when there are 2 queens in one hive?
Yes
Sometimes for whatever reason the old queen is unable to fly and bees will leave when a newly hatched queen emerges. Most times it is a mother/daughter queens,but I have read about sister queens coinhabiting a hive. But how do you really know unless the old queen was marked or they were genetically tested?
We have seen swarms with multiple queens , but in swarm season wh's to say two smaller swarms couldn't have merged? We think we may know,but the bees could always teach you something as they don't read the same books.
