The same happens in a single-column case. If you have a query like
"SELECT * FROM tbl2 where id2 > 'a'", once you've found the start
position of the scan, you know that all the rows that follow match too.

... unless you're doing a backwards scan.

Sure. And you have to still check for NULLs. Have to get the details right..
