In section 7.1 it says: "The :initform for a shared slot may be used when defining or redefining the class."

I think that this is the most directly applying passage for this issue. I am not entirely sure about the exact intended meaning of "may be" and "used", but at first glance it seems to me that this means that both the "SBCL way" and the "ABCL way" do conform. Portable code thus should not rely on either behaviour; it seems that whether :initform forms of shared slots are evaluated during definition or during first instanciation is unspecified.
