No, [Bout] is 720x480

bwdif in send_field mode means double rate deinterlacing. 720x480 59.94
fields per second interlaced input becomes 720x480 59.94 progressive images

Test it out yourself on the the Bout branch
ffmpeg -i "INPUT.VOB" -filter_complex "separatefields, shuffleframes=0 1 2 4
3 6 5 7 8 9,
select=eq(mod(n\,10)\,2)+eq(mod(n\,10)\,3)+eq(mod(n\,10)\,6)+eq(mod(n\,10)\,7),
tinterlace, setsar=sar=8/9, bwdif=mode=send_field:deint=all,
decimate=cycle=2" -an -c:v libx264 -crf 18 -t 00:00:10 bout.mkv -y
