Yes, this doesn't use cl-print at all.  And I think that makes sense:
when inserting a value into a buffer, readability is important (that
doesn't make a difference in your case, though).

We have different printers now in Elisp, and implementing
cl-print-object only has an effect when cl-print is used.

I dunno if that fact could be better documented to avoid this kind of
confusion.

Michael.
