As the helo translates forward, the tendency to yaw in the opposite direction to the rotors (counterclockwise rotors - yaw right) while applying power, is masked due to translational lift and the tail rotor becoming more efficient, this might even cause the helo to yaw slightly left if the TR is offloaded enough. To compensate, the pilot needs to put right boot in, but it is transient.
In a cushion creep, provided everything is in your favour, you can really detect this phenomenon. It is spoilt/masked eventually because the pilot has to apply collective(power) to stop hitting the ground as the a/c transitions. But you can take off from the low hover and in the right conditions with little or no application of collective at all.
