It is related because AUCTeX applies parsed information in a multi-file
setup to all involved files. Suppose you have something like this:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{graphicx}
\begin{document}
This is some text.
\begin{equation}
\label{eq:1}
a + b = c
\end{equation}
\include{Temp/sub-file.tex}
\end{document}
%%% Local Variables:
%%% mode: LaTeX
%%% TeX-master: t
%%% TeX-source-correlate-mode: t
%%% End:
--8<---------------cut here---------------end--------------->8---
--8<---------------cut here---------------start------------->8---
This is some text in a sub-file.
%%% Local Variables:
%%% mode: LaTeX
%%% TeX-master: "../mwe.ltx"
%%% End:
--8<---------------cut here---------------end--------------->8---
in this directory layout:
--8<---------------cut here---------------start------------->8---
.
├── Temp
│ └── sub-file.tex
└── mwe.ltx
--8<---------------cut here---------------end--------------->8---
Now, when you open sub-file.tex, AUCTeX applies the parsed elements from
../mwe.ltx to sub-file.tex and loads graphicx.el there, so you can do
'C-c C-m includegraphics RET' in sub-file.tex (and sub-file.tex should
also know about "eq:1").

I don't think this is documented in the manual in detail; it is more a
style writer thing.
