The reason is simple: Maven needs at least one snapshot repo configured, or it won't even attempt to ask anyone (specifically Nexus via the mirrorOf * setting) for any snapshots. Maven has built in an existing repository with the ID central but it is enabled only for releases. We must do either: 1) define another repo as snapshot only, or 2) enable snapshots for the built in central id. The example chooses 2. We could have used 1, but since I put in the example from years of habit, that's what stuck ;-)
You'll also note that I like to redefine the url as well so that when maven spits out what it's doing, it's immediately apparent if my settings are ignored or not.
