No they count as long as you are playing the wong in style the N0 was calculated for. You played those hands at a min bet of zero. The only compelling argument I have heard for HILO is the ability to count down two shoes at once. I have heard KJ talk of this and is imperfect so I am skeptical that playing with such errors really helps you much but you can zoom toward your N0 twice as fast until you wong in but your N0 will be higher by up to 30% or so over very strong counts. That is still likely to be an improvement in time spent to N0 but not by much.
