No, not odd - it's for EasyMod - it would replace the given code with "nothing" because there is no special instruction for it to delete stuff.
If you're doing the installation manually, you can comment out that part if you prefer not to delete it.. doesn't make any difference though.
I know the Recipient Addon does work okay though, I've seen it on a few sites. Can't understand what went wrong with yours..
Good luck next time round!
