The first type of picture is useful for "fake interlace" (needed to get a 25p video on DVD-Video because DVD-Video doesn't support progressive mode for example) or for scenes with zero motion in true interlaced video, and the other is for scenes with motion in true interlaced video.

Note: when I say "true interlaced video" I mean the kind of interlaced video that would give you those annoying comb artifacts during motion if you tried to weave/overlay its field-pairs into frames.

If so, does it mean y262 can't encode true interlaced video?
You have not understood interlaced support in Mpeg-2.
y262 can encode interlaced content just fine.
