Re: Why can redirection be combined in an assignment statement?

I am talking about combining just assignment and redirection, which
comes from these rules.

simple_command_element: WORD
| ASSIGNMENT_WORD
| redirection
;

simple_command: simple_command_element
| simple_command simple_command_element
;

Your example is not about this case. Therefore, it does not serve the
purpose of justifying combining assignment and redirection.
