iPad opening the flip case, wont answer the call

[zoran]

I have a SmartCaseFlipCover for my iPad and heres what ive noticed that did seem strange (or not). When someone calls me in Viber (or Skype, or Whatsup etc.) and the case is closed but an app is left open, when i open the case, it will direct me to the Viber app thats calling me. Only if no app is left open, i will be directed to answer the app thats being called. Does this make sense? Wouldn't it be correct, at the moment i open the case, to be directed to answer the app thats calling me?
I hope im describing it correctly... let me know what u think or if you need clarifications regarding the way im making the question.
