'copy-sequence' is usually not an adequate way to copy an alist.
It copies the backbone but not the associations.
When you modify the associations -- which you presumably intend to do --
the two copies will both be changed.
To copy an alist properly, you need to use 'copy-alist',
and that is why we added that function.
