Keep in mind that page is a few years old, but I assume they were referring to LFSCK Phase 2 (http://wiki.lustre.org/LFSCK_Phase_2_-_MDT-OST_Consistency_Solution_Architecture) which maintains consistency between the MDTs and OSTs.  One of the things that lfsck will do is make sure that the ownership info for a file’s MDT object matches the ownership of the OST objects for that file.  This is necessary to ensure that quota information reported by Lustre is accurate, but I don’t believe it is meant to fix any corruption in the quota files themselves.
