As long as your shared resources are in a component with the same GUID (i.e., your instance transforms do not re-GUID your components) yes, Windows Installer (and fusion for GAC assemblies) do keep a reference count. Bear in mind, however, that if you uninstall a patch for any instance files are downgraded (shared component ref counts don't guard against that) *unless*you are installing with MSI 4.5 and specify the Component/@Shared="yes" attribute.
If you are applying your instance transforms as secure transforms (transfor...@emea_instance) you do not need to specify them again even during uninstall. When you look in a verbose installer log (msiexec.exe ... /L*vx install.log) does the log say the action was skipped because the condition evaluated to false? After a product is installed (after InstallFinalize returns) the property Installed should always be defined.
