Why AND Array function gives true for empty array elements ?

In first the array control is empty the AND Array Elements function gives the result as True, is it correct  behaviour ? Explain me !
After inserting boolean conditions to the array control it works correctly.

Side note : what happens if you launch "Delete Recursive function" with an empty path as input :-o, be carefull !
