Previously in Underfoot, there could be 5x PHs for a particular named, but they might be spread so far apart that it wasn't feasible to pull all 5 to any single camp. The way that they split up spawn percentage, they give 1/5 of the probability they want the named to pop to each spawn, since there are 5 possible locations. So basically, if you could only kill 2 of these PHs from your camp, you'd only have 2/5 of the intended chance of getting a named.
I took the wording of the patch notes to mean that they had changed situations like this, so that all 5 PHs were closer to one another. In that way, they're consolidating them to one camp, so that the named appears to be more likely for anybody trying to camp it.
However, I haven't tried camping many named this week, so I couldn't really comment on how the change seems to be working in-game.
