This works for me, with git head from the day-before-yesterday.

ffmpeg -i one.mov -i two.mov -i three.mov -filter_complex "[0]
scale=426:720:interl=1,pad=1280:720:0:0 [a]; [1] scale=426:720:interl=1
[b]; [2] scale=426:720:interl=1 [c]; [a][b] overlay=426:0 [d];[d][c]
overlay=852:0" -an -aspect 16:9 -y ~/output.mov

Enjoy ;-)
