In one line

Which meter applies depends entirely on the table's capacity mode.

What gets missed

Provisioned RCU/WCU bill hourly at zero traffic, so that side is Time. On-demand RRU/WRU bill per request, so that side is Calls. Same queries, different meter. Storage and PITR bill separately either way.
