Not really. I don't look at it as an obvious hole in the training. I was saying that others may suggest that there was a hole. It depends on perspective. I have no desire to fight on the ground and I certainly don't want to fight in a ring. Chances are that I will never need to use my skills in a real situation and even if I did I doubt it would involve staying on the ground. From my perspective there is no hole.And so, training like their instructor is more important than addressing obvious holes in their technique.
So training like your instructor is only part of it. I would hope that all my students would surpass me in their knowledge and understanding as I have done with a number of mine. I am fortunate to still have a number of guys I look up to. I don't necessarily train as they train and I don't necessarily agree with all they say. But fundamentally the training is the same as it was years ago. The kihon is the same, the kata is the same. The interpretation or application is infinitely variable because that is what makes the system fit your needs. There are no right or wrong interpretations. If I was still in a system that didn't encourage the exploration of the kata then I would agree with your statement of training 'like your instructor'. That, to me, would be mind numbing and I would have given it all away years ago.
