That is correct.
For better clarification, in the Checklist, it says under Police Certificate, in 2 check boxes,
1. The country where you (or they) CURRENTLY live, if you have lived there for six months or more; and
2. The country where you (or they) have lived most of your (their) life SINCE the age of 18.
It was confusing when both would mean the same country. Say you were born in India, then left by the age of 18, to live in USA for say 12 more years (till present). With that, both check boxes would pertain to the USA, and not India as your first country of residence, before the age of 18.
But again, just to be sure and to avoid any delays, its best you submit for all countries you have lived since birth. This leaves no question on your background or security history.
