Some typo in 'Recovery Mode'

I found maybe some typo in '5.5 Recovery Mode.'

quote:
Ubuntu provides a recovery mode in case your system experiences problems. This is handled by the friendly-recovery package. If you select a "recovery mode" option on the Grub menu. This makes the initramfs pass a flag to Upstart which ensures that the /etc/init/friendly-recovery.conf Upstart job is the first job run after Upstart starts. As a result, this job has full control over the system and provides a friendly menu that allows users to check disks with fsck(8), repair your package database and so on.

The third sentence includes if-phrase only.
I guess this and the next ( = the fourth) sentence must have been a single sentence, but I don't know what you really wanted to write.
