Certainly.
After juggling, joggling, notching, or whatever you choose to call it, the timber is still very very rough, and needs to be flattened to a certain degree.
To accomplish this, you take your axe and score the face of the timber with shallow cuts about 3" apart, like you see here. You then take your axe and lightly chop at the face, removing the wood between the scores. This can be done with a broadaxe, or with a felling axe if you don't need an overly nice timber. This scoring and shaving should ideally remove any of the notches left over from juggling.
So a simple procedure is that you juggle to about 1/4" from the line (if you indeed snap lines at all. Something I find myself doing less and less as I work with irregular timbers) The you score the resulting rough and splintery face down to the line. You then take the broadaxe and shave off the wood right to the line. The scoring makes it easier to remove this last bit of wood, and removes the risk of the cut wondering where it shouldn't, and creating splinters. The scoring interrupts the grain, so that it does not pull your cut into the wood.
If you are making a timber that needs to have a smooth finish, you need to be careful that the scores don't go too deep. On a good timber you don't want to see the score marks like you do here. but on a barn that's OK.
When using the Central European method (Swiss, Austrian, and Hungarian mostly) then this notching is unnecessary, since the 'rough' face yielded by this method is smooth enough that you can shave it clean with a broadaxe without the need of scoring. I am not sure about the German method, but I believe it would be the same here as well.
Hope this helps!
