QueryReferenced vs. Query/Include

Designing new project. It will need some very heavy queries. To be able to design collections as optimal as possible for fast query results, am working thru (relatively new) additions to wix-data.

In docs on queryReferened(), it says:
" The queryReferenced() function can be used instead of a standard query() with an include() to overcome the limitations of the include() function. "

Could somebody shed some light onto which “limitations” the docs are referring to?

If you have more than one reference in the same table cell, you won’t be able to use include()

Ah, jeez, thanks, J.D. So much vagueness for such a simple issue. H/T.
