The initial post was regarding differences within the same mold, but there are also posts that compare different molds (see the image with the Wizard and the new Discraft putter). If we make the discussion wider the parting line will be important as a quick guide to how a disc may fly, but there are also models where the parting line would indicate overstability but in practice flies understable.
No one is talking about comparing different molds by using parting lines. There are too many other variables that affect stability to do that. Did you read the post that goes with the picture of the two putters? It says:

The purpose of parting lines is to be able to compare discs of the SAME mold, and determine which is more overstable. For example, if you were at the store looking for DX Teebirds, you should be able to line several up on the counter and accurately predict each one's stability relative to the others, by comparing parting lines. You CANNOT line a Teebird up next to a Predator and do the same thing because you would miss numerous other factors (speed, wing shape, bead, diameter, rim width, and others).
If you want to compare different molds, use the flight chart.
If you want to compare discs of the same mold, use parting lines.
