racehorse trainer riding skills

Question
hello madam, may i know why should every racehorse trainer know the basic riding skills, how would it help him?? my uncle said that a trainer who has basic riding skills can judge their jockeys ride in the race. if he's right, may i know how??

Answer
yes when they trainer knows how to ride then they can see and understand how they jockey is riding and why he is doing different commands. this gives the trainer an idea of what the horse is doing. also a lot of riders are rough with horses just to be rough. a trainer with basic riding skills will be able to tell this.
