Decided to give the wheel one more spin even though my status still shows as MLife Gold and Hyatt Explorist.
Before doing the match, I had Explorist level to February 28, 2019, and 3 Club Upgrade awards that expire in February 29, 2020.
After the match, I receive a message "you have already matched status" but (after logout and login) my expiration date was updated to Feb 2020. And I now have 7 Club Upgrade awards that expire in February 29, 2020. ^ ^ ^
That should be sufficient for my needs as the property where I stay most frequently (Houston) does not even have a lounge. And little chance I will be able to move up in rank, absent a Globalist fka Diamond challenge
