Getting the hang of it

After reading through the help file, I am still a little confused about what I am seeing with my zone experimentation.
On one camera I setup two zones, just split the view vertically right down the middle with Zone A on the left and Zone B on the right. On the alerts tab, zones a and B are checked and the ALL option is selected.

My understanding is that the alert should never trigger because ALL is selected and there is no overlap in the two zones. However what I am seeing is that ANY motion in either zone is still triggering the alert.

Am I missing something?

Bonus Question: If I want to do zone crossing do I have to enable object detection?
