That is correct. The lines that one obtains from the get_lines() method of
legend are completely new line objects. It is only upon the creation of
those lines (at legend creation) that the lines inherit the plot's line
properties.
Now, in the future, it would be nice for artist objects to have shareable
"styles", in which case an edit to a style in one place effects all artists
with the same style object. But that might be something reserved for
version 2+.
