Strange behavior of Android App [Alien Dalvik], [3.4.0]

I recently installed an Android App (ScummVM 2.2 from, build for Android). Contrarily to what I expected, the app is able to access the sailfish filesystem. Strangely, it is not able to access the android storage for Alien Dalvik.

How can this be? Did I mess up my installation or is this a new feature? I also have installed the app Alien Dalvik Control.

Did anyone else observe this for other Android Apps?
