What the documentation says is:

'If activated, prevents the overlays from showing in "save as..."
or "open" dialogs.'

I referred to the implementation as a "hack" because (1) the overlays
are also prevented for ordinary treeviews/listviews, and (2) they are
NOT hidden if the application filename happens to be "explorer.exe".

It's a freeware file manager:

The implementation was nontrivial because internally Explorer.exe
uses a proprietary treeview component that has to be duplicated
exactly using custom code. (This is why currently very few
applications support IShellIconOverlay when displaying folder
trees.) Some open source developers have been working on this
problem for quite awhile.
