I think  you are right here.  Since AFR depends on extended attributes for
file/directory synchronization, there is a possibility of data corruption.

A centipede was happy quite, until a toad in fun,
Said, "Prey, which leg comes after which?",
This raised his doubts to such a pitch,
He fell flat into the ditch,
Not knowing how to run.
