You will hear conflicting stories on this mainly because it is hard to "tell" someone rather than show them how to do it.
I remember when I first joined a club and saw one of the people who was new to bonsai raking the life out of the roots.
While I watched him do this he finally made the statement that he had never had good luck and that every tree he tried always died.
Well maybe what he was doing was the reason, hard to say.
Dissentangling the roots is important also knowing which ones to take out and which to leave is even more important without being species specific.

I would suggest taking some instruction with an experienced person to "see" how to do it.
