How to use Merge/Split Policy in ArcPro 3.3.1?

All,

So after completing an ESRI online training course it made me think about the split/merge policies you apply to domains. This is something I have never done and today I started to explore these capabilities, so maybe in some future data capture project I will be working smarter.

I seem to have failed!

I don't know if this is a bug in ArcPro or I have simply got the wrong end of the stick and misunderstood. I provide the geodatabase in a zip file with everything set up for you to see if I have missed something obvious.

I created a polyline feature class.
Populated feature class with 2 polylines, they are snapped to their endpoints
Added a SHORT field and set both to a value of 1.
Create a domain where split is to duplicate and merge is to sum values, I show this below.

I assign the domain to the code field.
Go into edit mode select both polylines and choose the merge tool then run the merge

The merge of the geometries works as expected but the code field returns 1 when I was expecting to see 2, what did I do wrong? Same result if I merge to existing or New feature.
