Strictly spoken, that's only a "side show" where the effect is visible.

The real key concept is that [] creates *one* object which is then 
assigned to the three names. That's the same for mutable and immutable 
objects.

But only the modification which happens on mutable objects turns it into 
a problem.

The rest o your explanation is 100% correct.
