Does anyone notch trowel both the tile and the substrate?

Depending on tile size yes I notch both but parallel to one another. Watch you tube video "trowel and error " showing how air gets trap behind tiles not allowing ribs to collapse properly

Thx. In that video it says back buttering is not necessary?
Some tiles need skimming to fill holes or pits. Like tumbled marble.
Most tiles don't required back buttering if the substrate is flat and has been prepped well.
You might need to back butter corners of tiles that change thicknesses like slate etc. You start tiling with the thickest of the lot, and in the lowest corner of the floor then.
Nearly all tiles don't require applying adhesive to the floor and the tile.
And pretty much all wall tiles don't require it. Unless the wall is rough in an area or something.
Got a picture of what you want to tile?

Personally I backbutter everything bigger than a metro, walls and floors, it's just a habit now...

Back buttering is essential with porcelain, it increases tile to adhesive bond by at least 50%
Adhesive has to be forced (burnt) into the pores of the porcelain.
Directional troweling is essential, ie both in same direction. Cross troweling can cause much bigger issues by leaving air pockets beneath.
If you’re going to watch trowel and error, watch the official one from the NTCA
The video above although produced by NTCA is woefully out of date.
