The problem is less about the station point not being centered but more about it being to close the image plane, which means your vanishing points are very close together. The station point is representing the viewer. So, what happens when the viewer/camera is very close to the object? The object appears very large and if you wanted to capture it in a single frame you'd have to use a fisheye lense, which are known for their cool distortion effects.
This video by Dan Beardshaw explains the topic really well.
Using this technique you'll likely see that the red rectangle is partly outside of the cone of vision, so distortion is to be expected
Also, it's generally a good idea to keep the station point centered. Usually it would only be off center if you took a photo and cropped it on one side. I was just being lazy in my example in my previous post, sorry =).
