At the thresholed wire lath in a single or double layer is bent to fit

THE MEMBRANE
Mud is trowelled on and pushed through the lath and a slight inward
slope is created.

Thanks for the reply! That makes total sense!

Would it be adviseable to put the lathing in place before I mud the
floor (with the thought that the floor mud would hold the lathing in
place at the threshold), or does it not really matter?

Another question I had was with respect to the threshold sides (and
top)... Is green-board sufficient, as a base for tile, or is
backerboard typically used in those places as well?


I would use mud on the threshold inside and top. You want no nails through
the membrane. I wrapped the lath over the top and down about 1" on the
outside of the shower, so that it would hold itself in place over the
membrane.
I nailed backerboard below that to help guide the trowel for shaping the
mud.

I did see a pro who glued some kind of backerboard (siliconized gypsum?)
to glued down membrane over the threshold. I believe he clamped backerboard
to the threshold to press the membrane into its glue to attach it, with
weights on
the top. He used special glue for this.
