(probably an unspoken assumption is that the two actions taught would both start in the same way, so one launches the attack, sees which* line gets closed, and continues in the line which has been opened. Even if you don't have the speed to properly determine the open line for the continuation, it's still possible to successfully run the pair as a mixed strategy and expect to find an opening stochastically)
* the same coach believes the most beautiful action is "feint direct, direct": at first you pretend to straightforwardly touch, but should your opponent fail to defend (because they're expecting a more complex action and are waiting to see where you're really going to attack), you go ahead and turn the "feint" into a real score.
Tactics; ways to attack.
