Hyatt Concierge via Twitter says that I should be able to upgrade my Hyatt status by matching status from MLife by completing the Opt In at https://world.hyatt.com/content/gp/e...tnerships.html

Every bit of wording there sounded like that page is to match Hyatt's status with MLife (so that your status gets upgraded at MLife) and not the other way around! Can someone confirm?
