No, because the implicit printed representation is actually
(PKG DESC...), not (PKG DESCS). In other words, the cadr of each alist
element is a single package-desc structure, not a list thereof. Both
the code and the docstring agree on this AFAICT.
Dotted notation is often employed in documentation in order to more
explicitly describe metasyntactic structure. This may initially confuse
users who see the implicit printed representation, but sooner or later
all Emacsites ought to learn that (A B) is equivalent to (A . (B)).

Done, thanks.
