This is exactly the reason, why btrfs (in case it behaves as claimed) seems to
be be in conflict with POSIX.
POSIX requires that stat() returns cached meta data instead of probably out of
date information from the background medium. In other words: It is not
allowed to return different data before and after a sync() or fsync() call.
