Variant Co-Occurrence table headings

Hello,

I’ve been looking at these 2 variants:

I can’t quite understand the column headings – columns 2 and 4 seem to mean the same thing, and then the Likely co-occurrence pattern doesn’t seem to make sense according to the data.

The column headings and the Likely co-occurrence pattern shown for the example in the blog are different and seem to make more sense to me (apologies, I’ve only just signed up and believe I can only post 1 snip).

Many thanks for any help anyone can offer!

These are the 2 variants:
2-152408249-C-T
2-152440229-G-A

This is the blog example:
