I'm busy getting ready to bake, so will have to come back for the rest - wanted to give a thought on this one. I wouldn't say those applications come from the forms, but that they are applications of movements found in the forms. They require other information, and the link isn't necessary.
For comparison, in NGA, this:
is taught as an application of this:
You'll notice much of the movement - indeed the actual method of applying the arm bar - isn't in the Classical form. But the principle is. So we can't at all say the Classical form teaches that application. You'd never get to that by just practicing the Classical form. But studying the Classical form will reinforce something about it (in the NGA example, the principle of the lock - in the TKD example, a part of the movement and perhaps the balance and transition with it).
As I said, if the link doesn't work for you, just ignore it. Use the form for what it works for, for you. You can absolutely learn the "applications" without the tie to the form (just as I could - and sometimes do - teach the wrap-around Arm Bar without the Classical form).
