He probably tried to figure something out for himself, not to actually improve the code.
In case you do this in the future, your code also gets saved when you just press save. Publish is only if you want to make your code (normally with improvements) public.

What's the point of this? You included my code but didn't improve it. You just added some junk that makes it even less readable.
