It makes no difference to how the walls actually connect.
All it does is show the connection on or not in plan view.
There is no need to change it while drawing a wall.
Generally you will want to leave it on all the time so the connections display correctly.
But if you want to see the true wall extents with no auto-connections, then you can turn it off.
But I would say you would rarely want to do that.
