True - up to a point.
My suggestion is that you do a couple of tests your way and give this one a try as well: For both the root stock (that's the term I'm most familiar with) as well as the branch you wish to graft, choose the 'woodiest' parts on both.
The denser the 'bark' (for lack of the proper terminology) will allow you to make your cuts into the inner part of the plant which is where the 'grafting' will eventually take place.
Sorry for my bad verbage - I know what I mean! LOL
Hopefully it will make sense for you as well.
