I don't think we too far. 

For sure, we paginate even if CSS multicol properties are not used. 

And, if you by "pagination happens along the block axis" mean that
page breaks occur due to constraints in the block direction, yes.
Here's one of the examples in GCPM:

  html { 
    overflow: paged-x;
    height: 100%;
  }

The setting on 'height' is a constraint in the block direction and is
the cause for page breaks. Without that constraint, there are no
pages; unless you constrain the element in the block direction,
pagination will not occur.

Now, these page breaks result in a strips of content with fixed
lengths. Much like columns. For us, it was natural to reuse the
multicol implementation, but there are no ties at the spec level.

I think we agree. Let me try to restate: "paged-x" and "paged-y" only
describe how pages (that have been created due to constraints in the
block direction) are placed in relation to each other; "paged-x"
results in a horizontal stripe of pages, ane "paged-y" results in a
vertical strip of pages.
