You should see a difference depending on whether the rules are connected by "Or" or "And" logical
operators. You can easily test this with conditions such as
"1=1" Or "1=2" (should evaluate as true since the first condition is true, i.e. the condition is fulfilled, formatting executed)
"1=1" And "1=2" (should evaluate as false, since the second conditions is false, i.e. the condition is not fulfilled, formatting not executed)
