At stationary, would the two propellers be providing thrust at opposite directions, with one towards the rear and the other towards the front so as to provide the counter torque?

As forward flight increases, part of the counter torque may be provided by the rudders, thus allowing the both propellers to provide forward thrust, but still with one stronger than the other.

Does it work that way? Thanking in advance anyone who could shed some light on this.
According to Wiki: Conventional helicopters use tail rotors to counter the torque effect of the main rotor. The starboard propeller of the X³ has a higher rotational speed than the port to counter the torque effect.
