### Background

I am using dvc with tensorflow. I have two versions of my model which are different enough to merit their own git branches, i.e. they have different architecture definitions and different data generators.

To run experiments, I `git checkout` each branch, make my changes and queue up an experiment. I have two branches so I end up queuing up 2 experiments. Then I call `dvc exp run --run-all -j 2` to run them both in parallel.

This is basically what `dvc exp show -a` looks like (don’t pay attention to the metrics and params):

```

### Question 1

How do I interpret the lines next to the experiment names? It looks like `exp_1` experiment correctly connects to branch\_1, but why does it look like the `exp_2` experiment connects to both branch\_1 and branch\_2? Did I set up these experiments incorrectly or is this a display bug or what?

### Question 2

My other more general question is: is this the intended workflow for managing experiments on multiple branches? Any comments on this question from a dvc expert would be very much appreciated.

## Thanks!
