Snowflake metadata: bytes scanned & scanned bytes

Using the Snowflake UI - after a given query has completed - one has access to the History tab in order to access/examine corresponding metadata.

Something confusing occurs when I compare the Bytes Scanned field (see via History tab and Image 1) to the Scanned Bytes (see via clicking query ID hyperlink and Image 2)

Why are these different? Do they mean different things?

As far I know, this "Scanned Bytes" shows total bytes read from Snowflake tables. If you are executing a COPY command, it's normal that you see zero bytes (I also see it shows 0 when querying secure views).
