You are correct. 

From my Solution Definition:

"When updating the RIPE database, it is already possible to submit a Punycode 
encoded value (i.e. with ASCII encoding) for an email address value, but this 
change automates the conversion of any non-ASCII encoded email address to 
Punycode."

This automated conversion will allow any email address with an IDN (non-ASCII) 
domain name to be stored as Punycode.
