I guess the question is rather why to *use* arbitrary symbols for ordered
lists. The only use case for that I can come up with is visual design. The
"box-corners" counter style you mentioned before seems to be a good example
for that.
So what special meaning could be put into the list markers, which needs to
be reflected by screen readers?
