But this doesn't answer my question. I'm wondering what happens here:

() { unsetopt localoptions; setopt promptsubst; }   # prompt restored

Doing this I'm able to set promptsubst in caller (which used emulate
-LR). This looks like: option-scope of (anon) is equated with scope of
caller. Is it really what happens?
