Cleanses tend to be abilities with rather short cooldowns, and they will no longer be able to remove protected Balance/Madness damage-over-time effects. Some examples of cleansing abilities are Cure, Field Aid, Toxin Scan, Triage, Restoration, and Expunge (formerly known as Purge).
Purges tend to have longer cooldowns and can usually only be used on yourself. In addition, purges will continue to remove the protected Madness/Balance damage-over-time effects. Some examples of purging abilities are Evasion, Dodge, Force Shroud, and Resilience.
Working as intended.
