Sheyda,
The link is correct, the version in the tool just hasn't been updated. The relevant new option is:
http://bazaar.launchpad.net/~percona-toolkit-dev/percona-toolkit/2.2/view/head:/bin/pt-online-schema-change#L10895
Or, just download the 2.2 preview: http://www.percona.com/downloads/TESTING/percona-toolkit/2.2.1/
