clearing recent apps is it required? does it do anything?

[AC Question]

I am running an HTC One M8 and when you hit the double square icon it brings up all your recent apps.

My question is does clearing the app from here do anything?

When I reboot the phone this list doesn't clear, shouldn't it?

Below is my convo with HTC:

@HTCHelp @HTCUSA does closing apps from this screen accomplish anything?

HTC: t clears your running background apps.

It will clear the open apps. However, apps will start to reopen if the apps are opened. Are there apps in particular that you are concerned about.
