Suppose it requires horizontal scrolling after enlargement. The scrolling is only one-dimensional (there’s no vertical scrolling required because it fits within the viewport), and thus it meets your one-dimensionality condition but it requires horizontal scrolling and thus shouldn’t meet the proposed SC.

AC: 
If it fits within 320px, you should be able to zoom 400% from a desktop size, and it will fit larger mobiles with some zoom. If it isn’t fixed with, then it won’t scroll out of the viewport.

The approach of using a minimum width (instead of zoom factor) means that aspect is less important.
