"rhgb quiet" controlling the display of commands in single user mode ?

Why does removing "rhgb quiet" from the kernel boot parameters control whether or not the commands I enter are displayed in single user mode ?

For instance, if I do not remove "rhgb quiet", when I am in single user mode, whatever command I type will not be displayed on the screen.

The commands will work, but nothing is shown.

Eg: ( entering whoami as the command )
sh-4.2#
sh-4.2# root

NAME

       plymouth - A graphical boot system and logger

DESCRIPTION

       plymouth is a graphical boot system for Linux which takes advantage of the kernel-based mode setting (KMS) available for modern graphic
       cards to provide a seamless, flickerfree and attractive boot screen. It allows to choose between various, static or animated graphical
       themes to spruce up the startup and avoid the noise generated by the vast amount of kernel messages while the machine boots into X. On
       systems where kernel-based mode setting is not available, plymouth falls back to a text mode boot screen which provides a simple progress
       bar to pro- vide feedback during boot.

       In order for the configured default plymouth theme to be loaded during boot, the option `splash' (or `rhgb' for backward compatibility with
       the RHGB boot splash) must be provided at the kernel command line. Without this command line option, plymouth will default to showing
       detailed boot output.

       During the boot process, the user can switch between the graphical theme and the detailed boot output using the Escape key.

AUTHORS

       plymouth was originally prototyped and named by Kristian Hogsberg, originally written by Ray Strode and has had significant contributions
       from Charlie Brej. It has also had contributions from Peter Jones, Adam Jackson, Frederic Crozat and others.
