The scenario you describe is not officially supported by the AppBuilder companion app, which is meant for developer testing purposes only. Should you need to give your app to testers, we recommend building your app with ad-hoc provision and distributing the .ipa directly.
The LiveSync url does not expire in the AppBuilder Windows and In-browser client as the built is kept in our cloud and there is no designated sync like with the Visual Studio extension. The VS sync would trigger deletion of the project from our cloud and its reupload, so the built .ipa is basically deleted.
