Where does it do that?
(LOCAL should not have anything to do with IGNORE).
The code we have in MariaDB 5.5 is:
if (ignore ||
handle_duplicates == DUP_REPLACE)
This has nothing to do with LOCAL.

As LOCAL and IGNORE are independent flags that have nothing to do with
each other, I can't answer your question.
My previous answer should cover most things about using or not using IGNORE.
