The reason is a simple race condition. Initially the test tried to synchronize with master before showing tables, but it turned out that the slave should fail at this point, so synchronization was removed along with the bug fix for MDEV-11288. But slave is still expected to replicate one table before failing, so we need an intermediate synchronization.
