Similar to the Israeli ambassador being recalled from Dublin. They mean it as a big dramatic statement but they've done it that many times it's lost all significance.
She only gets reinstated again for the purpose of making another dramatic exit.
I suppose looking at it from the Israeli government's perspective, Ireland is a very safe place for Israelis and Jewish people in general, but the public and government are vocal on Israel's actions and there's no defence/intelligence links between the two countries. Trade links are on the European level.
There'll never be a reason for them to send a skilled diplomat, so may as well send a shit stirrer who's only good for causing controversy.
