Just wanted to see if it was correct that my Lifetime MR points decreased by 40000 when I bought back Platinum. Anyone else can check their buyback and Lifetime MR points to see if they decreased for you too?

I queried it by email with MR as this wasn't stated in the offer that Lifetime points would decrease and got this response...."The balance of points transferred to other Marriott Rewards accounts are no longer on the source account and do not count toward Lifetime Elite status. Points deducted for any Elite Buyback purchase also do not count toward Lifetime Elite status, so if you select to buy your status back then the points used will be deducted from the Lifetime points balance. "

I don't get that as I thought it would work the same as a stay redemption certificate which doesn't decrease your Lifetime MR points.
