What happens when 2 iOS apps contain AU extensions with exact same AudioComponentDescription?

I'm considering releasing a new version of the app as a separate app on the App Store. If both apps contain AU extensions with plists providing the same componentSubType and componentManufacturer, will the system guarantee to detect only the AU extension with the latest version?

This is important because I want the users to reopen their projects in hosts and have the newer version of the plug-ins loaded.
On further testing, it seems, the version number is irrelevant. Looks like OS picks the extension with the latest creation date of the binary.

This is still a guess though. Would be good to get some sort of a confirmation from Apple regarding this.
