I have to agree with NZquilter - this is a reversed photo, not bad staging. Well, there is bad staging as well (behold the two spools of thread on top), but the pillar is on the left because the photo is reversed.
I've never seen a left-pillar domestic machine. Any pictures I've seen online were reversed (often on Craigslist from using the wrong camera on their phone). There are a couple of shoemaking machines with a left pillar, but they're very rare.
