The article mentions varying ability to picture things. You may have good spatial reasoning but less visual imagination. I know that when I picture something in my mind it isn't always a clear image, often just a shadow of the thing I'm imagining. I find spatial reasoning has a different quality, it's like sensing the position of your arm but you can apply it to objects that aren't a part of you.
Yes, spatial reasoning and visualisation seem like two separate unconnected subsystems, even though it seems like they should be related.
I seem able to do the spatial just fine, and the visualisation not at all.

Very good, yes it's exactly like this. I know, but I don't need to see. I can explore the model or plan, and know how the result will be, and still don't need to see!
