This question is a bit like "I drove my car into a lake and it drowned -
why was it designed to do that?".  It is not a silly question, but most
drivers don't try and also don't ask.

Ok.  `self-insert-command' is a command to insert the character a key
corresponds to - "Insert the character you type." (from the docstring).
It operates on the level of single (key) events, not key sequences.

So instead of binding a complete key sequence Z h a o to
`self-insert-command', so that when you have finished typing those keys
Emacs would insert "Zhao", each of the individual letter keys are just
bound to `self-insert-command'.  The command is intended to be bound to

In that way this command kind of an exception.  For more see the
implementation: it just looks at the last event.
