I don't think that's the case. Standalone Garmin units have had the feature for years. I suspect it comes from the Garmin system, but isn't integrated into the Pilot's software.
The reason I believe it does...is because it changes (the dash speed display) literally as soon as you pass the sign...and only when you pass the sign. Unless the signs are gps synced...?

The 2018+ Accord and 2021+ Odyssey read speed limit signs using the windshield-mounted camera only.

From the 2018 Accord service information:

"The traffic sign recognition system scans road signs for the speed limit by using a multipurpose camera unit attached to the upper middle part of the windshield. It displays the information in the gauge control module (multi-information display (MID)/head up display), which allows the driver to recognize a current speed limit."

The 2019+ RDX obtains speed limit information using GPS coordinates and map data only.

My 2019 MX-5 Miata and 2020 CX-5 display speed limit information using GPS and the camera. The speed limit normally comes from the GPS, but if there is discrepancy the camera-recognized limit is displayed instead.
