The problem being that there are left handed and right handed 90 degree IEC connectors. At least in our requirement, that is. But not in how they are made. This desire for left and right is preposterous, in the real world. That real world where thin flexible power cords are the norm.
Audiophile power cables are stiff, mostly due to design... and don't have sharp turn or bendability. So the left or right handedness of the given connector becomes the biggest part of the implementation, and thus one has to have twice as many 90 degree power cords available, than one might think. No two companies put the female IEC connector on their chassis, in the same direction (top vs bottom). There is no standard implementation, here. Unless it has a fuse connection/socket built into the IEC connector, those types generally have a specific IEC plug orientation.
So it becomes a 'produce on demand' scenario as many to most power cord companies (cable companies) are not big enough to keep duplicate sets of 90 degree power cables in stock at all times.
Straight out the back is not such a big deal, as it can be flipped over 180 degrees, generally, with no real obvious problems in making connections. Most of the time.
