The definition of "passthrough"?

I’m getting conflicting information here.

On one hand the manual seems to indicate that the “passthrough” tickbox is equivalent to disabling the rule, but then some of the examples suggest that the rule would be evaluated, but instead of stopping after this rule RouterOS would keep going on to the other rules down the chain.

So… what actually does the passthrough tickbox do?

Mangle passtrough ?
Passtrough=yes, packets processed furhter to mangle rules (probably might be remarked with another mark, if traffic matches configured parameter, if no than accepted for furhter actions).

Passtrough=no, no tip, packets are accepted for further actions and they excluded from mangle ruler after it.
