Because shell calls pop-to-buffer, whose doc string says:

Select buffer buffer in some window, preferably a different one.
...
If `pop-up-windows' is non-nil, windows can be split to do this.

Try:

emacs -title ${TITLE} --eval '(let ((pop-up-windows nil)) (shell "shell"))'

The --eval command line option calls the eval function, which takes
exactly 1 argument (a lisp form).
