The only clarification I've seen is from the config itself:

Module names listed in "global" section will have symbols globally
; exported to modules loaded after them.

That is, you need to understand that the resources of modules specified globally will be available to all other modules. Unfortunately, I have not used the global section anywhere and I cannot evaluate the effect of this section in practice.
