That's not the link to the I-765 instructions. I-765 instructions are here.
What you linked to might be a version of the I-765 instructions that were supposed to be used with the August 2020 fee change rule, which was blocked by the courts in September 2020 before it came into effect, and was never implemented. (There is a note about it on this fees page.) As far as I can tell, that edition of the instructions was never used. The current as well as previous two editions of the I-765 (here and here) do not have the text you quoted.
