Encoding Context Update

Does a “Encoding Context Update” require a indexed representation with ‘0’ index and then a “001 <command>” or this is just an editorial mistake in not deleting this part of the spec.

So:

This is the description for Indexed Representation:

An _indexed representation_ with an index value of 0 entails one of the following actions, depending on what is encoded next:
 o The reference set is emptied.
 o The maximum size of the header table is updated.

And this is description for Encoding context update:

An encoding context update causes the immediate application of a change to the encoding context.

 Context Update
 An encoding context update starts with the ’001’ 3-bit pattern.

But doesn’t really mention indexed representation. Based on the bits used, I am guessing the indexed representation was not updated? Please clarify, thanks.
