Probably because \ is "already" documented as being an escape
character, allowing the string to be taken literally by the shell,
hence skipping possible aliases in this case.

The closest form of documentation comes from TLDP [1]:


The alias command will list your current aliases. You can use unalias
to remove the alias (to disable it just for one command add a “\”
(back-slash) before the command)...
