Multiple Info.plist files and UIApplicationExitsOnSuspend

I have three Info.plist files: one for release (Info.plist), second for release testing (Info_release.plist) and third for testing (Info_test.plist).

In other words, I generate three separate applications from same sources so that all can be installed in a device at the same time. Therefore the content of plist files are identical, except CFBundleIconFile and CFBundleIdentifier.

When looking at Info.plist in XCode I can see "Application does not run in backgr" with a checkbox, while the two other plist files show UIApplicationExitsOnSuspend. Open all three files as source code or text and they contain exactly the same code:

<key>UIApplicationExitsOnSuspend</key>
<true/>

Weird... still everything seems to work ok. Just a note. Btw official documentation is available here.
