11. Vrnasu tsuzuke da also expresses the idea "to keep doing s.t." and can
be used in place of Vrnasu ppanashi (with intransitive verbs), as in [8].

Vrnasu tsuzuke da cannot replace -ppanashi when the preceding verb
is transitive.
111. Vrnasu tsuzukeru also expresses the idea of "to keep doing s.t." and can
be used in place of Vrnasu ppanashi, as in [9].

Vrnasu ppanashi (with intransitive verbs), however, does not express
the actor's volition while Vrnasu tsuzukeru does. Thus, Vrnasu
ppanashi is not acceptable in [lo].
