Yes. (In the version I gave, the replacement of the second $, the one
in the s command, by \n was superfluous.)

In the original version, the x command matches up to the end of the
line, but the resulting selection is no longer itself a line; so the
subsequent s command, trying to match various things and then the
empty string at the end of a line ($), does not succeed.

But replacing, in the x command, the $ by \n leaves the result of a
match (now one character longer because it includes the \n) a line, in
which the s command then successfully matches $.

As ever,
Mark.
