To the best of my English-speaker knowledge, global, universal, and
context-free all mean the same thing, at least for practical purposes.
Technically, "universal" is just "global" at a scale bigger than one
ball of mud, but they mean practically the same thing since (to the
best of my knowledge) all English-speakers involved in creating and
sharing names happen to be on the same planet or in orbit around it.
Context-free really means "no matter the circumstance or situation, no
matter where or when", which is exactly the same as 'universal'.
So I am baffled by your claim, here.
As I understood it, the point of putting 'nicknames' on that edge not
touching 'securely unique' was to show that they are global but not
securely unique - that, when used in a context-free manner, a nickname
such as "Mark Miller" refers to more than one entity, but none of them
