Because you NEVER have an unsupported long (vertical) joint between
drywall and drywall, drywall and backer board, or backerboard and
backerboard.
I understand that, no problem. It's one of those 'I can show
you better than I can tell you' things. For sure I know that
drywall/etc needs to have the edge land on a stud.
Any flex will damage the joint. There IS an option when a
wall is open. Add another stud at the point the 2 panels will join.
That was one of the three solutions the guy mentioned.
What he said. And that you don't tape the seam between sheetrock and
backerboard. Tile should completely cover the backerboard.
The last sentence is actually what I was asking. I didn't understand
just *why* the backerboard has to be covered by tile and not just
taped/whatever to match the drywall.
I'm just going to live with the tile extending farther by a course
past the shower. Thanks for all the advice.

I seems like you received a lot of very good answers, you understood what
each of the answers and options meant, and you came up with a final plan
that works for you.
I just wanted to add that if by, "I'm just going to live with the tile
extending farther by a course past the shower", you mean that there will be
one column of tile that is past the shower and runs down to the floor next
to the tub, I think that may be a good idea anyway.
I have two apartments, almost identical, one directly above the other. I
re-did the bathroom in the 1st floor apartment a year ago, and I am re-doing
the bathroom in the 2nd floor apartment now. When I re-did the bathroom
last year, I did it so the tile came right to the end/edge of the tub --
with no tile coming out past the edge of the tub. This year, before
starting on the 2nd floor bath, I looked at the 1st floor bath and I noticed
a minor problem. Since the tile only runs to the end of the tub, there is
no column of tile along the wall next to the tub running down to the floor.
Due to that, small amounts of water run down over the edge of the tub, and
since there is no tile there, it runs along the sheetrock wall next to the
tub. That causes the paint and sheetrock to peel a little. Not a big deal,
but still an issue.
So, with the 2nd floor bath, I am intentionally adding a column of tile out
past the edge of the tub and down to the floor. That way, any small amounts
of water that run down over the edge of the tub will run down a tiled (not
sheetrock) portion of the wall. That will eliminate the problem I have with
the 1st floor bath.
