I think it is consistent, but the rule is different.
start-translation-timestep is not called for _implicitly_ instantiated
contexts since their instantiation occurs _after_ the general
start-translation-timestep phase.  For _explicitly_ instantiated
contexts (like \new Voice ...) I think it is being called.

No guarantees, but that's the way I remember.
