It actually causes just two objects to be created.

This one is a new and different thing that is not related to your
above two lines of code at all.

I think what you are missing is that a literal String creates a new
string object. The fact that the characters are the same doesn't mean
it's the same object:

It actually only causes one object to be created, see above.

A possible misunderstanding here would be to miss the difference
between an object and a variable. A variable is a reference to an
object. Several variables can reference the same object. Assigning
variables only changes what they reference, not the objects
themselves.

I think that having objects be a separate concept from the variables
that reference them is pretty common, and provides very nice language
semantics.
Just think that a literal string is a new object every time it
appears, the same with hashes, for example.
