Would running 2 nodes reduce chance of winning?

[pluto2021]

For redundancy purpose, in case one goes down, the other would be still running. Say the setup is properly configured: only one with UPnP true and the port 8444 is forwarded to one node only. Assuming both nodes are connected to a same set of HDDs with a same number of plots and a same access time to the plots, would this reduce the chance of winning?

When a match is found, how is that communication being sent? say to the node the port is forwarded? or to both nodes? any guidance from or documentation on how this process is exactly functioning?
