Why yacc_EOF is used as a list_terminator for for_command?

Hi,

https://git.savannah.gnu.org/cgit/bash.git/tree/parse.y#n800

for_command contains the following rule.

| FOR WORD newline_list IN word_list list_terminator newline_list DO
compound_list DONE

https://git.savannah.gnu.org/cgit/bash.git/tree/parse.y#n1147

list_terminator is this. I can see why '\n' and ';' are included. But
it doesn't make sense to me why yacc_EOF is needed here.

list_terminator:'\n'
| ';'
| yacc_EOF
;

It may be useful to include yacc_EOF in other rules. But Is it correct
to include it here?
