How are implied rules implemented with a multi-layered policy?

When an option is selected in the Global Properties / Firewall page, certain rules are created that get merged with each policy installed to any gateway. In case of multi-layered policies, does this merger happen with each layer defined in a policy or is it just to the first ordered layer? for e.g. if "Accept ICMP requests" is selected with "Before Last", will the ICMP rule be inserted only in the first layer of each policy or in each layer.

 

In case the answer is first layer, then what if the first layer is shared and used as last layer in another policy.
