Why does the Torah write "K'naf Aviv" and not 'Ervas Aviv' like in Vayikra, 20:11 & 29:21?

Ramban: Because, whereas there, the Torah is coming to sentence the sinner to Misah or Kareis, here it is placing a curse even upon someone who degrades his parents,

which applies even to someone who merely uncovers the nakedness of the woman that his father took under the Chupah.
