Please don't say 'most SD is upper field first'. That is 100% not true in the US, where it has been lower field first for generations.
We live in a society!

Now that you say it that way it makes sense. Given DV is 480 not 486 in the NTSC world if 486 is upper odd line first then lopping off 3 lines from the top and bottom would mean an uneven number of lines were dropped hence DV lower even field first. I never bothered to think it about it that way.
