they all go out to different armatures in different directions. they were constructed with one inlet on each side, and since they were going to different sides of the same room it made sense to splice them in a junction box somewhere on the middle.
edit: to elaborate a little further everything is connected in parallel and there were a lots of outlets in this space as well. five of these branch out, only one of them is going “in” to feed the rest.

Ohhh! I thought it was 3 in 3 out, okay 1 in 5 out is a bit better though I hope you’re not daisy chaining any further than that
