A generated ACE label become a received ACE label  once it leaves its mother
application and arrive at other applications/dns servers in the outer world.
Therefore,the two distinctions merely express two aspects of one ACE label in its trip from application to applications.

If you received unknown-nameprep-made ACE email addresses from others,
they are "saved" in your addressbook/mailbox. Should we call any received
IDN email address as  "query" (???, why?)  which may have no lookup sematics within email clients?   

If you type new native web address into your browser, they are ACEed and
sent to the dns and webservers. the ACE label is "saved string"(???, why?) 
for for browser, but "query" (right!) for dns and webservers.
