Yes, because when dpkg replaces existing files, it doesn't follow symlinks. It
always replaces the destination with the new file/symlink. A file being removed
is also not followed, the actual symlink is removed. Just think of symlinks in
the /usr/doc directory being the same as the symlink in the (linked)
/usr/share/doc directory.
