The common ground is a problem but it also depends on cable length. Basic problem is then there is a flank on one of the signals ground bounce in the receiving end. With differential signals ground current stay there it is and it will not affect the other signal. You also need a differential receiver. It is important current at transitions are between differential signals and not the ground.
