Yes, that's correct.

The passage is correct, but is ambiguously phrased.
You appear to be parsing it as:
Python lists are mutable sequences. They are very similar to tuples,
but {{they don't have the restrictions} due to immutability}.
which would imply that Python lists are both mutable and are immutable.
Instead, I think the intended parsing is:
Python lists are mutable sequences. They are very similar to tuples,
but {they don't have {the restrictions due to immutability}}.
implying that Python lists are mutable; and then contrasting lists
against Python tuples which have “the restrictions due to immutability”.
Does that help?
You might send the publisher a request to clarify the text in a future
edition.
