Currently, if I create a filter having the code

false & false & false & false & false

and then make an edit in any page, the filter's page will have a message saing
"... it consumes 5 conditions of the condition limit."

There is no reason for it to consume the last 4 conditions, because the first one is already false.

Notice the behavior is a little better if the code is changed to

false & ( false & false & false & false )

because it will now consume just 2 conditions. Ideally, it should consume only 1 condition in both cases (see [[Short-circuit evaluation]]).
