No, match merge rules doesn’t take XREF into account unless its explicitly told.
So for your case, you need to create a Match path on XREF table and add match columns from that to your match rule.

Thank you for the helpful information.
I also searched and found this: Path Component
It was said that this is not the best practice, but a workaround nonetheless. I noticed that this case is similar to my case, but with different match rules. Would you agree with the mentioned thread or not?
Ervin, i agree to mentioned post that in an ideal scenario the BO to capture all the vital info. So in your to do that you may want to capture the FULL_NM in a child table with all possible variations. You need to design your Datamodel with that thoughts before hand.
Though not ideal, within the existing boundaries what you may have already, going with XREF matchpath should serve you to meet your needs. Also in my mind the XREF matching is not very different than a transitive match which MDM allows already.
Could you elaborate more about the first paragraph in your latest reply? About "capture the FULL_NM in a child table with all possible variations". Also how about the other fields like GOV_ID, BIRTH_DT, and GNDR_CD?
I think the idea is to capture the information that you expect in the XREF to be made available in the child table and use the child table data for match and merge.
On another note, in your use case you mentioned that you want to do an exact match on Full Name, but in your example Jane Doe (Source 1) matches and merges with J Doe (Source 2).
Also, if you had fuzzy rules on Full Name, so your Source 3 record should match back to Source 2 record, as the if A==B and B==C then A==C i.e. if your original 2 records matched on fuzzy rules in the first place; and if your incoming 3rd record is equal to the 1st record; then 2nd will match with 3rd.
Match process happens only on BO record whatever is there in XREF does not matter
Match will happen on BO, If you want Matches to happen on BO records,
Please create the match path on Xref rather than BO.
