It might assist those on the border of reception if they have the correct orbital slot before searching.
It is up to others how they wish to configure their E2 receivers, if they wish to edit the satellites.xml file that is up to them.
For my personal use, I select which satellites and frequency bands I wish to be represented in the satellites.xml file and accept the contents.
I think that the satellites.xml creator tool of "Huevos" takes a regular online feed from Lyngsat or Flysat as the basis of its database.
In which case, the orbital numerical values in the satellites.xml file would be aligned with the data source unless there was any post download adjustments via a script.
"Huevos" would be the person to confirm these points.
