Both sides can be facing you when you work a row. In stockinette for instance, the knit side is the RS so when you knit sts across, you're working on the RS and it's facing you. When you purl sts across you're woking on the WS and that side is facing you. When you have worked across the ws row and are done with it, you have 'ended with a wrong side row'. Then you turn to work the RS and that will be facing you. That's why the instructions 'ending with/facing...' can be confusing, it depends on whether you've turned the work at the end of the row or not.
