I believe this is to show the security inspection team the documents have been verified and they can proceed through screening. Some places stamp " DOC CHECKED" or some other notation. Think it just verifies the customer name and passport information match.

If that was the case every boarding pass would have a similar marking.

It is facility specific. You see different methods in different airports for verifying documents have been checked. Ever fly to CDG and have the sticker placed on your passport? How about GRU does a sticker also. Each airport take a different tact at verifying documents
