There are some pics floating around here, but the way I always see it described is that when you are drinking from a glass, you know how you are drinking from the near side of the glass, not the side opposite you? That is what you should be doing here, knitting from the nearest side. So turn the sock right side out, and try it that way.
However if you prefer it that way, knitting on the far side of the circle, there is no reason not to continue, having the sock come out inside out is no problem, sometimes it is beneficial: I know many people do stranded colourwork this way to keep the tension good. You can simply turn things right way round when finished, or when you need to carry out a complicated manoeuver.
