There is a factor associated with a trailing throttle where engine braking causes a locking of the rear wheels, a lightly feathered throttle as the spin starts will help minimise the effect, but if you are already going too fast, it may not be an option.
That's why declutching helps - removes all torque from the rear wheels, acting in either direction.
And _that_ is one of two reasons why manuals are fundamentally handier than autos in the snow.
