Windows Phone 8.1 embedded string resources from PCL

As I read - for Windows Phone 8.1 XF - here 'due to the WinRT default trust level, embedded resource loading from a different assembly will not work unless the ReflectionPermission on the source assembly is correctly set. This permission cannot be set on PCL assemblies.'

I have a WPP8.1 project with a referenced XF PCL lib. This PCL lib HAS embedded resources (for string localization), and when I run the app in emulator, it CAN read from embedded resources (localization strings work perfectly). So, is this note only for real devices? Or...?

Thanks to all!
