Don't forget each jet also applies a force to the body, not just resolving to a torque. Just remember that all forces (including reaction forces) and torques must be resolved in order to determine the net. It doesn't matter how you choose to resolve them, but some methods simplifiy the means to a solution.

Turning off the rocket which is next to the ground, does not resolve to the same net result. Remember that a balanced torque couple has no net force on the free body.

If you are interested in this sort of thing, then a first year text book on mechanical engineering dynamics will be a good read for you. Usually, the principles will be covered in the first couple of chapters. Personally, I found this sort of material really fun to study, and intuitively satisfying.
Good good study, day day up!
