After re-order line, insert a blank line, change order first and second hyphen

Question

My Previous question post in
How can I get a line break After each name change
A good solution that works well has been proposed by Toto Thank You
but, sometimes I can change insert one line after the second hyphen "-"
When I change the order by interverting the order between the first and 2nd hyphen
I want to get this:

before:
Bob Cleatry - August - 6325.32 - Portland, OR, United States
john Cleatry - October - 7289.25 - Portland, OR, United States
Alan Cleatry - Novenber - 12.582.00 - Portland, OR, United States
Peter J. Finley - September - 5312.00 - New Jersey, United States
Peter J. Finley - October - 7325.00 - New Jersey, United States
Peter J. Finley - Novenber - 8240.00 - New Jersey, United States
jack Norton - October - 12425.60 - New York, United States
celine Norton - November - 13328.32 - New York, United States

Re-order With Regex:
First Step 1
Find: ^(.+?)\s-\s+(.+?)\s-\s+(.+?)\s-\s
Replace: $2 - $1 - $3

Nota: I Append space before and after hyphen "-" for éliminate name Compound, Composite ex: jean-claude and hyphen in URL etc...

After Step 1.
August - Bob Cleatry - 6325.32Portland, OR, United States
October - john Cleatry - 7289.25Portland, OR, United States
Novenber - Alan Cleatry - 12.582.00Portland, OR, United States

Answer 1

You might add a step before the re-ordering, matching all lines that start with for example:

^(.+?)\s-\s.*(?:\R\1.*)+

Regex demo

Then in the replacement, use the full match surrounded by a newline.

\n$0\n

For the second step, you can use the approach that you already use in the question.

---

Assuming there are no newlines already, and if you don't want to add extra newlines at the start or at the end of the string when replacing, you can use a conditional replacement.

Find what:

(?:(^)|\R)((.+?)\s-\s.*(?:\R\3.*)+)(?:(\R)|$)

Replace with:

(?{1}:\n\n)$2(?{4}\n\n:)
