First trigger fires after your update operation got over.

Second trigger fires before your update operation starts.

(Not sure...Hope its correct)

I think both are same. See the description from microsoft below.

FOR | AFTER

AFTER specifies that the DML trigger is fired only when all operations specified in the triggering SQL statement have executed successfully. All referential cascade actions and constraint checks also must succeed before this trigger fires.
AFTER is the default when FOR is the only keyword specified.
AFTER triggers cannot be defined on views.
