This property is intended to display the primary installation folder in Add/Remove Programs. I'm not sure how it makes anything easier during upgrades, as evident by the problems you're having. But it's just for display. What exactly are you trying to use it for?
TARGETDIR is a required property, so an empty string is not supported. You should not be setting TARGETDIR directly using AppSearch, but instead set a different public property and then schedule a type 51 CA (see CustomAction/@Property attribute) to set TARGETDIR condioned on whether that AppSearch was set; otherwise, set it to something different (generally you should always set this explicitly, or at least never install any files directory to TARGETDIR or any child directories that are not otherwise redirected, like ProgramFilesFolder - doing so can lead to your files being installed to the root of the fixed drive with the most free space available).
