If you are still unsure of the why, then you have had a fortunate life. There are many times you will get a set of "instructions" where somewhere something is wrong or incomplete, but you won't know that until you've worked your way through them. Ikea comes to mind. It is often very helpful to read through all of the steps involved first to make sure you actually have all of the parts/pieces you need and to make sure they make sense before starting. So I say again, that if you've never run into one of these situations, then you've been lucky.

I’m not questioning that you should read all the questions, I’m saying it’s ambiguous what you should do if you’re given the following task list:

    1) read all tasks
    2) do x
    3) do y
    4) do z
    5) now that you have read all tasks, just write your name and do nothing 

I don’t understand why I should not do x,y,z. Task 1 is telling me to read all tasks, not to execute any. Why should one, when reading 5), decide to execute that particular one, but not the other ones?

To me, the correct procedure would be to read all tasks (task 1), then continue executing task 2), etc.
