Panorama Pre and post rules

[blackpier365]

Pre rules post rules in panorama of palo alto firewall 1..if post rules and pre rules have already configured in panorama and then  we add another palo alto 2 in panorama which has post and pre rules as well which one it will select ?|
Does pre rules of palo alto 1 changes and inherit pre rules of palo alto 2 in panorama ....and does post rules of palo alto 1 changes to post rules of palo alto2 firewall..

Can anyone comment on this  Panorama

Rule evaluation is top to down if Device Group is nested - https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000CljVCAS

If Device Groups are not nested then rules from Device Group 1 don't affect firewall in Device Group 2.
