I also believe this.
Its like each concierge was told to gift EP to best clients and they have a certain number to hand out at their best discretion, without too much input from AA.
This was probably agreed on mutually from AA and Hyatt when partnership was announced earlier this year. AA immediately gave Globalist to CK, and now Hyatt is using up their Quota before the end of year.
I would guess the number of CK is higher than the number of Hyatt's Invitation only program, so that's why we are getting it.
