No. You don't need to forget them. And you aren't forgetting them when you move from the simple version to the full chord.

This is because the simple version is just a small part of the full chord version.

Simple C major chord:
E |--0--|
B |--1--|
G |--0--|
D |-----|
A |-----|
E |-----|

Full C major chord:
E |--0--|
B |--1--|
G |--0--|
D |--2--|
A |--3--|
E |-----|

See we are just adding two more notes to the simple version to get the full version. Make sense? :)

There are many, many different ways to play any given chord on the guitar. We just started with the simplest possible versions so beginners could get some music happening as soon as possible. After that, we gradually increase the complexity of the content as the courses move forward.
