I'm assuming this is the case because you are telling xfs_db to run in read only mode... Why? Because an actively modified filesystem is only coherent on disk when you consider all the modifications staged in the journal, and xfs_db ignores the journal. Hence what it reads of disk is not coherent and hence is not guaranteed valid.
