That's just when things aren't moving though. When things move at a multiple of 1 pel per field in the vertical direction even the best deinterlacers being used at the moment are not going to be able to make something sharp out of the result ... the object becomes identical (ignoring the shift) in both fields, all the image data for half the lines in every frame is simply gone, interpolation will have to do. So in that case the effective resolution becomes 50% ... but it's aliased, so it's actually a little worse than 50%. Which is why you really don't want to do high movement video with interlacing (sports mostly, since action movies are of course shot with flicker cam, making interlacing moot).
