Yes.

Neither. Its just that your quotes above do not capture the context.

If the author requests calcMode="discrete" then they get a discrete
animation.

If the author requests calcMode= some other value, that gives an
interpolated animation, then this will only succeed if the path data is
compatible. If its not, then the spec prohibits falling back to a
discrete animation, because that would contradict the authorial intent.
Instead, the animation does not happen (unsupported value).

It means the same as all the other instances of "unsupported values".
