It is correct if you want multiple icons per rule. The colon is used to separate multiple icons for a rule. If you want only one icon then use first_non_empty to pick the first 'contains' that returns a value.
That said, checking the code I note that an empty icon file name, as in your example, isn't handled very efficiently. I will fix that.
