Two "Trunk name" entries when creating a trunk?

When creating a trunk, there’s two places for user input with the same identifier called “Trunk Name”. One at the beginning and another one in Outgoing Settings. Are these the same? If they are different, is there a problem with the dialplan if the same “name” is used for both? I think that if they serve different purposes then the identifier “trunk name” should be different.

This is seen in the all current versions of FreePBX.
