201.2
Text that refers to the object it's on by name means just that particular object and not any other duplicates of it, regardless of any name changes caused by game effects.
201.2a
If an ability of an object uses a phrase such as "this [something]" to identify an object, where [something] is a characteristic, it is referring to that particular object, even if it isn't the appropriate characteristic at the time. Example: An ability reads "Target creature gets +2/+2 until end of turn. Destroy that creature at the beginning of the next end step." The ability will destroy the object it gave +2/+2 even if that object isn't a creature at the beginning of the next end step.
201.2b
If an ability of an object grants to an object an ability that refers to the first object by name, the name refers only to the object whose ability grants that ability, not to any other object with the same name. Example: Saproling Burst has an ability that reads "Remove a fade counter from Saproling Burst: Put a green Saproling creature token onto the battlefield. It has 'This creature's power and toughness are each equal to the number of fade counters on Saproling Burst.'" The ability granted to the token only looks at the Saproling Burst that created the token, not at any other Saproling Burst on the battlefield.
201.3
Two cards have the same name if the English versions of their names are identical, regardless of anything else printed on the cards.
