I do not know how true it is.
I have heard this explanation also and I have to say I don't know. If your teacher does not want you to read about dzogchen before receiving an introduction, then don't do it. Pretty simple.
If you have a teacher whom you can ask, then do. If you don't have a teacher, and are wondering whether or not you "should" read such a book, well, the decision is up to you, isn't it?
It is also true that a person, who has no teacher, may be attending his/her first dzogchen retreat, has read nothing, knows nothing, etc, etc. may benefit immediately from such an introduction. It can also happen that nothing whatsoever occurs and perhaps only a seed is planted for the future. Who is to say?
I am of the opinion that is is perhaps better to know nothing, have read nothing, etc. etc. But that is because that is how it was for me. I don't know how it is or will be for someone else.
We are all living in an age where information is everywhere and readily available. That is how it actually is. In some ways, this makes it easier for us. In other ways, it is more difficult.
If you want a definitive, you should or shouldn't, I don't think there is such an answer. You can take guidance from someone else (your teacher) but in the final analysis, it is your life, your karma, etc. etc.
I wish you luck.
I am well aware of my idiocy. I am also very aware that you too are an idiot. Therein lies our mutuality.
