If I understand your use case correctly, the following will work as well
Open a new tiddler and write:
{{{ [all[tiddlers]tag[City]tag[Germany]tagging[]tag[Company]] }}}
tag[City]tag[Germany] : Get ALL Tiddlers that have tagged with "City" AND
"Germany"
tagging[] : For Each result "X" in the last step: Get all Tiddlers that
tagged with "X" (all tiddlers that tagged with any German Cities)
tag[Company] : For Each result "Y" in the last step: GET only those
tiddlers that tagged with "Company" (may be you've other things in that
City)
Regards
