It's simply that when the input is:

  mkdir builddir && cd builddir

the function shell-directory-tracker fails to see the cd command.

I recently develop the habit to call successively:

  mkdir builddir && cd builddir
  # do some work
  cd ..
  rm -rf builddir

repeatedly. If initial value of the default-directory variable is
/home/matthias/Projets/argos then after 4 iterations it will have been
updated to /, and with the fifth it will be /..

I observed the same behavior with Emacs 27.1.  No regression!

Comments in shell.el says of directory tracking that: "This is basically
a fragile hack".  Confirmed.
