474 to doji ni / to itte rno
two actions or events are not momentary actions or events. Thus, to torno ni
is acceptable in [3] but not acceptable in [4].

Note that if a noun precedes to d6ji ni, to torno ni can replace to d6ji ni even
if the two actions or events are momentary, as in [I]. Compare [I] to [5]
where verbs precede to d6ji ni.
