Rules and line breaks

Returning to this topic,

re: climbingstars’s neato ‘process a rule’ trick to run a rule/rulebook without the extra linebreaks:

To process (RL - a rule): (- ProcessRulebook({RL}, 0, true); -).

I just wanted to ask, what does the above code actually do to the rulebook? Does it follow it, consider it, abide by it?.. etc.
