Is there a reason to put ever put summing stacks in a folder stack?
It all depends on your mix and how you like to organize your tracks.
Assume you have 10 tracks of background vocals. 5 of them, you combined as a Summing Stack (to create and control them like an Aux Group. But now you want all 10 Tracks, the five in the Summing Stack and the other 5 Tracks combine together in a Folder Stack so you can control them with the Main Track of the Folder Stack, which functions as the VCA Master Fader.
Please pay attention that the 5 individual Tracks are assigned to the VCA Group but only the Main Track of the Summing Stack is assigned to that VCA Group, not the Subtracks of the Summing Stack, which makes complete sense from a mixing point of view. Logic understands that and automatically takes care of that.
It may sound complicated, but it is basic routing workflow and engineers on large mixes usualy use VCA Groups that they put conveniently in the center, so they don't have to scroll half a mile to the left or right to get to some Tracks.

Why not just put summing stacks in a summing stack instead?
Because it doesn't work. Only Summing Stack are allowed inside a Folder Stack, but no Summing Stack in other Summing Stack.
