If I understand things correctly, "GetSelf" is like saying, "Okay, which item reference started this script?" and "MySelf" is a generic name given to the answer to that question so that they can include that item reference in a script with little effort, especially since that item reference will be changing depending upon which item starts the script. Kinda like taking a nametag from little Suzy and giving it to little Tommy and refering to the kid as "He who holds the nametag, whoever that may be".
