About New Topology Analysis Method

[Jedore]

In STAM, New Topology Analysis Method is metioned as https://skywalking.apache.org/docs/main/v9.3.0/en/papers/stam/#new-topology-analysis-method. And I can't understand one statement:

unless there is another different Peer network address <-> Service Instance Name mapping found. 
In that case, only generate relationships of peer network address <-> service name and peer network address <-> Service instance name.

Can any one just interpre ? Appreciate it very much!
