This is because async export code only tries hard to copy buffer-local
variables (`org-export--generate-copy-script'). Global bindings are not
transferred.

I am not sure if transferring global bindings is something we should do.

The existence of `org-export-async-init-file' implies that user may want
to use different settings from the Emacs session. If we start
transferring the full Org-related Emacs state to async process, users
with custom `org-export-async-init-file' might be affected.

On the other hand, your use-case clearly shows that the current behaviour
can be confusing.
So...
Confirmed.

One possible way to fix the confusion could be adding a new
`org-export-async-preserve-global-state' variable. When non-nil, we will
transfer global state in addition to the buffer-locals.
But I would like to hear other opinions first, if there are any.
