I don't understand what the "composed" rule means?
A "composed" rule is one of "composed icon w/text" or "composed icon w/no text". Rules are evaluated on a column-by-column basis. If a rule is "composed" calibre will collect whatever icon(s) the rule returns and then go to the next rule for that column. In other words, calibre composes a large icon from the icons returned by the composed rules. This composition stops when a non-composed rule that returns an icon is encountered, after the icon(s) returned by that non-composed rule are added to the composition.

As for mistakes, it depends. If a non-composed rule returns an icon when it shouldn't, further evaluation is stopped. If a rule does not return an icon when it should, evaluation continues. If an advanced rule is broken, evaluation continues. If the rule returns the wrong icon you get the wrong icon.
