I feel like I'm not understanding something correctly: Why do we only split one cell each time, and how do we decide which of the two cells to split? For example, why is the blue box not split into smaller boxes as well?

I had the same question as above. I do believe we split both, but for pedagogical reasons they chose to split only one side.

We chose this simple example where only one box needs splitting at each level. In general though, any number of splits is possible.
We don't split the blue box in this case because we have reached the minimum number of objects, heuristically chosen to be ~3 in this example.
