From the website:
Effective June 3, 2021, to obtain a Disney Vacation Club Membership Card, Members must accumulate a total of at least 150 Vacation Points purchased directly from Disney Vacation Development, Inc. Disney and Concierge Collections options are not available for ownership interests not purchased directly from Disney Vacation Development, Inc. after March 21, 2011, and, effective April 4, 2016, Members who have not purchased an ownership interest directly from Disney Vacation Development, Inc. will not have access to Membership Extras.
I take the red part to mean anyone who purchased resale prior to 4/4/2016 is grandfathered in. The change that occurred on June 3, 2021 reflects the increase in the number of direct points needed to qualify for Member Extras from that date forward.
