Answer: Yes, forward progress is fine, but the "Requirements" sometimes has other elements that must be accomplished beyond the minimum comment count. In this case, the submission is fine, however the other Requirements should always be kept in mind before submitting. Using this prayer as an example, it's possible to have threaded out 20 comments towards the defeat of an ayakashi but not actually focus on the dying elderly at all. Such a thread would not have been accepted.
