Yes, the same thing, but usually it would not appear at the left side, but the right, as the one on the left would act as the color burst when the horizontal phase is slightly delayed. I think it is less likely that the phase could be pulled so far the other way, but maybe. I wish I had a source of this signal so I could try it on the CTC-5.
