But you did not put \\ in a DynamicsStaff context, so it has no suitable
container where it could place separate Dynamics contexts.

First you have to figure out what you want to happen here.  Do you want
two Dynamics contexts with different orientation and settings?  In that
case, you'll need to provide a superior context aliased to Staff where
it can anchor those Dynamics contexts.

If not, you'll want to filter out the \\ completely.  It's probably
easiest to do that using \tag and \removeWithTag, but of course it is
also reasonably easy to do this using a music function.
