For the first time i tried to print vase mode (in 2.1.1) , but when i set outline perimeter to 1 and vase mode there are still layer changes.

But if i set to 0 perimeters and vase mode, then it goes in a slowly z-spiralling mode.. but with strange artefacts in the g-code IF it is NOT a "possible" model.

Then the next time i go into settings it is back to 1 perimeter, but still goes spiralling.

Is this normal, or is it me not understanding it correctly?

Im not really sure. I have only had limited use for the spiral mode so ive only used it a few times but when i did it worked fantastic.
