Подробно опишите своё предложение:

Там пример вообще неправильный.

Описаны отличия euid/ruid от suid, а не отличия ruid от euid.

https://en.wikipedia.org/wiki/User_identifier

eauid используется для определения доступа к ФС.

ruid - The real UID (ruid) and real GID (rgid) identify the real owner of the process and affect the permissions for sending signals.

А вот suid - да, при сохранения uid при понижении привилегий.
