there are different ways of air layering according the thickness of the
branche and the species of the plant
you can cut a ring of bark as thick as the diameter of the branch
is, remove teh bark and make some more carving on the cambium
you can strangle under with a wire that fits in a carved ring
and apply hormon and sphagnum
you can instead cut scales and put a stone and hormons and spagnum
to keep the scales open
you can make half a cut and put a plastic sheat in between like a
credit card blade and sap will not flow trough this part and make
roots only from this side ..
you can bent a bench e keep it in the soil with a fork to roots
it all depends why you are making air layering and which result you
are looking for your possibilities of action

cut cut
There is a bottom cut, but not all the way through at
the two cut sites. They are stuffed with moss,
wrapped, and cut off when roots form on either side of
the above indicated airlayer. My question is whether
roots also from on the piece more towards the branch
tip.
They do. Or at least did on my one try at it. I didn't bother to save
it, thought, because it was an uninteresting branch.
This seesm to be a variation on the
put-a-pebble-in-a-slit-and-bury-in-the-ground
technique. but on that one the roots form at the end
of the growing tip.

Based on the biology of trees (plants!) and how nutrients, water, etc.
are moved around, I cannot imagine how you could get roots in both
places; you might be in danger of getting roots at neither place.
It works. I did an upward-growing branch on a ficus this way.
Obviously, the base horizontal branch was sacrificed beyond the first
cut. I did the two cuts, put thin strips of plastic into them that
extended beyond the cut edges to keep them open. Dusted it all with
rooting hormone and packed it in peat moss. Worked fine.
When I had roots I liked, I cut the horizontal branch off at the cut
farthest from the trunk, and then the other one. Shaved bark on the
bottom of the remaining bit of the horizontal branch where more roots
grew over time. Planted the layered tree and grew it until 4 years ago
when I gave it to a friend as a gift.
_I_ would not risk it in a plant that I really wanted to get at least
one layer off of. Do the bottom layer now, then the other layer in a
few years when the new roots are fully supporting the new plant.
The method of this approach is detailed in Naka "Bonsai Techniques 11"
on page 3. I did it pretty much as he explained it there with the
addition of the plastic pieces. I was concerned that the cuts would
heal so I made it impossible.
