APA7 citing multiple authors

The author checklist for a journal I'm publishing in says the following about their implementation of APA7:

---
When there are 3 to 5 authors, use "et al." only after all authors have been cited parenthetically once.
---

This is not the behavior in Zotero.

For example:
Franklin, M., Niemi, R., & Whitten, G. (1994). The two faces of tactical voting. British Journal of Political Science, 24(4), 549–557.

is cited the first time in text as:
(Franklin et al., 1994)

Is the journal's style guide just idiosyncratic (it claims to be vanilla APA), or is there something I'm missing here?
