You're correct: AND matches both conditions.
As originally written, the first entry in the list "www.somedomain.com" does
not match the first condition. It does match the second condition, though.
So the OR is true because the second condition is true.
The second entry in the list has the same logic: the first condition returns
true, and the second condition returns false. Since the first condition
returned true, the OR returns true.
The code doesn't want to match ANY of the patterns. It needs a truth table
like this:
www * result
0 0 0
0 1 0
1 0 0
1 1 1
That truth table matches the AND operator. Does this make sense?
