Is MIUI v4's task killer the same as what Greenify does?

Mar 17, 2014
I was wondering if the task killer that pops up when you hold the home button is the same as what Greenify app does? I can't seem to find any info on this so I'm asking here. In case you don't know, what Greenfiy does is the same as going to the app's info page in Settings and pressing Fore Closse.
