passthrough check box

Morning

I need some help understanding something
In the mangle rules, under action, there is a check box for passthrough

What is its purpose, i know what the action passthrough is and i think i have an idea then what this check box is then suppose to do but i’m not sure

Could someone please enlighten me on the subject

Thanks

passthrough - ignore this rule and go to next one (useful for statistics).

statistics and marking packets.

that is for the action passthough…what about the check box one…surely there has to be more to that

Sorry.. That can be confusing.
From manual. http://www.mikrotik.com/testdocs/ros/2.9/ip/mangle.php

passthrough (yes | no; default: yes) - whether to let the packet to pass further (like action passthrough) after marking it with a given mark (property only valid if action is mark packet, connection or routing mark)
