Concerning the similarity between the reorderings produced by both MT systems and those in the reference translation, out of 9 directions, in 5 directions the NMT system performs a reordering closer to the reference, in 1 direction the PBMT system performs a reordering closer to the reference and in the remaining 3 directions the differences are not statistically significant.
nMT generally produces reorderings which are closer to the reference translation.
