H1b To H4 COS with H4 Visa Stamping

Hi Folks,
I changed my status from H1b to H4 (Approved with EAD)
Based on the info provided here,
https://travel.state.gov/content/travel/en/News/visas-news/important-update-on-waivers-of-the-interview-requirement-for-certaing-nonimmigrant-visa-applicants.html

From what I understand, If my previous H1b has not expired within the 48 months, even though I am changing my status to H4. I am still eligible for Interview Waiver based on

Other nonimmigrant visa applicants applying for any nonimmigrant visa classification who:

*** Were previously issued a nonimmigrant visa in any classification, unless the only prior issued visa was a B visa; and**
*** Are applying within 48 months of their most recent nonimmigrant visa’s expiration date.**
*** In all cases, applicants must meet certain legal requirements to qualify for an interview waiver. Implementation of this authority begins January 1, 2024, and will be reviewed annually. This authority is in place until further notice**

It also mentions,
*** As a reminder, applicants renewing a nonimmigrant visa in the same classification within 48 months of the prior visa’s expiration date continue to be eligible for interview waiver until further notice.**

Which means there is no change to H1b extensions on dropbox.

Any one else understand this differently?
Thanks for any help.
