Your interpretation is correct, at least for wood studs. Here’s a link to a technical paper we wrote on the subject several years ago (2003) after receiving an interpretation from the ASCE 7 Wind Loads Committee:
We have codified this approach in the Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings, 2001 Edition.

Subject: Main Wind Force vs C&C Wind Force
A senior associate and myself are having a debate.
So please correct me if I am wrong:
Desinging a wall element for out of plane force (be it masonry, wood, etc.)
When checking the element for forces that are combine, (i.e. axial + wind) one should use the MWFRS forces. However that same element must then be checked for the C&C load, but that C&C load is not required to be in combination with any other loads.
If this is incorrect please let me know, also if anyone has a reference that would show an example of this I would be greatful.
