The Demdex call is used to generate the MID value to be stored in the AMCV cookie on the user's browser. Any ID values – MCID(AMCV cookie), UUID(demdex cookie) and any declared IDs sent by the customer along with associated properties like authentication states, co-op safe/unsafe etc. are stored with MCID calls.

Hope this helps!
