I think the code in its current form would get mighty confused :)
I only imagine this happening when multiple instances of the same
widget are running on the same computer. In my case this is not often
(never to date).
Otherwise I reference the state data for any given widget by

widget_control,widget_info(find_wid('specific_tlb'),/CHILD), get_uvalue=state

This of course will still suffer the same problem when two or more
instances of the same program are running. This is something I will
have a think on though.

If I am only running a single version of a GUI (and associated popups)
then I try and avoid generic names for the uvalue. If I am using a CW
I am usually passing in the uname. Works well in these situations.

Cheers
Andrew
