First, the thread is mis-titled. He's not teaching Silva how to fight (that's just silly), he's simply acting as one more trainer hopefully extending Silva's tool box of techniques. How much applies, imo... all of it. How much will Silva be able to make use of in his next few fights? Little if any, unless there is a tonne practice/sparring using them. Fights move too fast, there is little thinking/planning going on, it's mostly reaction and it takes time to incorporate new skills properly in a real fight.
