In the source's own words

“Grammar text is sent only to the selected local, on-device, localhost, or private LAN backend when grammar is enabled.”

What it measures: The sentence describes where grammar text goes. It applies when grammar is enabled.
What it does not show: The row counts a private LAN server as local, as the page does. A user who points grammar at a hosted endpoint would be outside it.
