Thanks Philipp.

I had tried with very tight t-table limits, even with a limit of 1 for both
words and pos tags and still it didn't work for this example sequence. This
was surprising.

I hope I can avoid shorter phrase-lengths because the task I have in mind
would require me to have default phrase lengths at least at the POS tag
level. And, would like to avoid using factored model as backoff too because
I would like to encourage those translations that have a particular pattern
of POS tags.
