When it's in your left hand, you're knitting onto the right hand needle, if you are looking at the purl side of that stitch (the bump), that's what they call a purl. Regardless of how you made it, if the purl side is facing you, it's a purl, so knit it. That's what they mean.
You knit the purl facing you if you're doing seed stitch. If you're doing ribbing, you'd knit it....
