The one-liner command does check if the current installation is really a Debian Wheezy installation to prevent users from accidently executing the command on other operating systems or other Debian versions.
I think it's the easiest way to just add wheezy-backports to get the requirement nodejs installed. If (advanced) users don't want to use that way, they could compile nodejs for their own.
This nodejs version will be installed from the debian-backports repository (as of the time of this PR):
root@git-ce:~# nodejs -v v0.10.29
