Supplementary explanation follows.

AUCTeX has two schemes of installation.  (I'm sorry if you already know
this matter.)

[A] Traditional scheme using configure, make, make install
In this way, system administrator can perform system-wide installation.
All the users on that machine share the common default settings,
including `TeX-parse-self'.
On the other hand, individual normal user can perform personal
installation with this scheme, by giving suitable options to configure
script.  The default value of `TeX-parse-self' only affects that
particular user.

[B] Modern scheme, namely ELPA
This scheme always makes personal installation.  Although this is not
exactly the same as the personal installation of [A], only the
particular user who executed installation from ELPA is concerned about
the default value of `TeX-parse-self'.

This story refers to the system-wide installation of the above [A].

This is [B].

I hope this information be of help to clarify your thought.
