Xcode has been self-contained since Xcode 2.5 specifically to support multiple installations: Prior to Xcode 4.3, you could have multiple /Developer folders installed. With Xcode 4.3 and later, everything is inside Xcode.app, and you can have multiple Xcode.app versions installed.

One reason to support side-by-side Xcode versions is to make it safe for developers to try out newer and even pre-release versions.
As long as you're using SCM, you'll be able to revert any changes that do prevent you from using multiple versions of Xcode on a project. Those kinds of changes, however should only happen in response to user action. (For example, by upgrading a xib file to Xcode 5 format or using iOS 7 features.
