Ah, you're misunderstanding what's going on.

GLOB_ASSIGN has the effect that

v=*

expands * at this point.  The value of v contains all the files.

GLOB_SUBST has the effect that a variable is expanded at the point where
it's substituted.  So without GLOB_ASSIGN, or equivalently quoting the
value assigned to v,

% v='*'
% setopt globsubst
% print $v
<files>
% unsetopt globsubt
% print $v
*
