Yes it does. OK, that means Tom's original suggestion of checking
the other table for the same value before updating it should prevent
an infinite loop, providing that's done from a pair of 'after update'
triggers, using the NEW.column entries in the triggered table to update
the other table.
This tested OK in both directions.
Of course, if I need to do any manipulation of the fields in the
table being updated by the SQL command, that will require a separate
'before update' trigger.
