Probably, NNEDI does keep original pixels. Don't know about its internal procedures, but documentation says it 'interpolates the missing pixels using only information from the kept field'. Considering its speed looks like it doesn't do it some dumb way. It wouldn't work good at plain deinterlacing in some critical cases (e.g. one field black, the other white), but at bob -> resize -> interlace the same example somehow should work.
