Describe who would be a native-born citizen that would not qualify for natural-born citizen status. USCIS explicitly states:
“restore the status of native-born or natural-born citizen (whichever existed prior to the loss) as of the date citizenship was reacquired.”
Interpretation 324.2 Reacquisition of citizenship
When would one be native-born but NOT natural-born?
Note, though, that the State Dept. specifically informs us... “In any event, the fact that someone is a natural born citizen pursuant to a statute does not necessarily imply that he or she is such a citizen for Constitutional purposes.”

“When would one be native-born but NOT natural-born?”
There isn’t a time. The use of two terms in a manual does not mean there are separate meanings for each one. Nor does a State Department manual override the US Constitution. One is either a natural born citizen, or a naturalized citizen, or not a citizen at all.
