Motivation: we'd like to programmatically specify the version name/code (i.e. to include the build number from the build server). However, this means that we cannot specify version info in the AndroidManifest.xml file, as this takes precedence. Not doing so makes IDE use more difficult, as the IDE gets version code 0 and won't install over an existing non-IDE version unless you first force a downgrade to an IDE build from the command line. This flag allows us to specify a very high version code in the AndroidManifest.xml file, making IDE builds take precedence, while still allowing us to override this info when performing command-line (official) builds.
