You can additionaly decide by other factors unique to your leaves and not branches

- Like if your leaves have open boundary but the branches are closed
- Or since all your leaves have exactly 5 polys and 10 boundary points so if none of the branches do you can use that also to distinguish them
- or in case they have uvs and leaves and branches are already in different udim or clearly separated section of UV tile
- or average normal length will be much closer to 1 for flat leaves than for round branches, should be enough difference to find a clear threshold value
...

Essentially find the qualities that you think are the most robust way to distinguish leaf from other geo and you can use that when you run over the connected pieces, ideally consider all the models you want to apply it to potentially come up with a test that works for all if possible

Fuse SOP -> Poly Path SOP

that will get rid of overlaps, and will join each branch into a separate curve

seems to work fine here 22.0.408
