I don't think so.  The problem is that repeats now support putting the
\alternative phrase inside of the construct since that is a saner way of
doing things.  But the previous way is still supported for compatibility
reasons.  Your input file could be interpreted either way, and the way
LilyPond interprets it is not the one you intended.

This is a design problem I think, and not a matter of you misreading the
documentation.  No idea what a long-term resolution would look like.

You can likely write

\repeat unfold 8 { ... } \alternative { } ...

in order to quench the \repeat unfold's thirst for an alternative.

It would probably be better if the default resolution was in direction
of the new syntax, but I don't think that this is trivial.
