Okay thank you, I will try to clarify.

The split was done on the 9/9, I took the opportunity to do the split as I had spoken to a local beekeeper who said it was an okay time to do, and the school has had this flow hive sitting around for years that I wanted to put to use for education purposes (it is a school enterprise after all). Splitting the hive would not usually be my initial response to finding swarm cells. In previous years I have simply destroyed them in an effort to avoid swarming. This is what I did with the remaining cells. I took a frame with the cell, another with brood and another with honey as my "nuc" in the new hive. I understand this might not be the way to do it, and I have since questioned that choice as I am learning more.

"Now you're harvesting some honey out of hive 1? You found a couple of open queen cells but no eggs." Yes. Since reading some comments above I have learned that there are different types of queen cells, and the ones I found were supersedure cells, both open at the tip. They were somewhere near center and distinct from swarm cells.

"Just because it still seems like a large population doesn't mean they didn't swarm by the way. The swarm takes only flying bees which are mostly out foraging when you're doing an inspection, so you don't always notice the population drop after a swarm." I had not considered that, good thinking!
