The result is pattern A will play for its whole length, transposed by the note value on step 1 of pattern
B.
Then pattern A will play for a second time, transposed by the note value on step 2 of pattern B.
And this will continue for all 16 steps of pattern B - giving you a means to sequence 16 repeats of
pattern A, each one with a different transposition.
Plus P
The "xpose by trk n+p" event is much the same as "xpose by trk n".
The "+p" is there because the note value used from the target track is taken after any playlist
transpose is applied.
If you're familiar with playlist transpose, try editing the playlist on track 2 to transpose pattern B, and
see what the effect is.
