Isn't it ^(.*)a(.*) rather ?

This is the normal behaviour.
You don't get all possibilities of how the string could be matched, you 
only get one.
In your case you have two couples of parentheses, so you capture two 
strings. Your "shouldn't I get 5 strings" doesn't really make sense.

This is what you get if you use (.*?) (ungreedy)

This is what you get if you use (.*) (greedy)
