To clarify: this is in the "" manual, the node "yank nthcdr
Exercises".

After reading that node, I don't see where it describes the behavior
incorrectly.  What it describes is what M-y does after C-y, and that
didn't change.  What _have_ changed is that now M-y can be invoked
after a command other than C-y or M-y.  This new behavior is simply
not mentioned in that node.

When did C-y and M-y NOT yank text with its properties?  I thought it
was always the case?
