what does (once) mean here?

This enumi is a bit surprising to me. The options are suggestion shown with bank
name, or server suggestion with bank name? AS a non-expert in this domain, this
is confusing. Is there no option for nothing displayed? And what is the
difference between the two - where does the first suggestion come from?

logged once per page load. It's detailed in autofill_metrics.h

Suggestions can be local suggestions (which are saved on local and not sync to
payment server) or server suggestions.
