You are reading it wrong, they are describing a method that you could
use to create a full backup after every commit. However, they also stat
that "only the truly paranoid" would take that approach, and that a
more sane person would do incremental backups after every backup, and
complete "hot-backups" over the week end, or something like that.

You're free to decide a backup strategy for yourself. Subversion gives
you a lot of flexibility on that point.
