can you elaborate how?  it surely should:

$ mkdir omg omg.wtf
$ cd omg
$ pwd
/home/roman/omg
$ cd $PWD.wtf
$ pwd
/home/roman/omg.wtf

`cd foo bar` does not "move laterally", it's like `cd ${PWD:s#foo#bar}`,
except `foo` is not treated as a glob.  this doesn't look lateral to me:

$ mkdir x
$ cd x
$ pwd
/home/roman/x
$ mkdir -p .$PWD
$ cd / ./
$ pwd
/home/roman/x/home/roman/x

no, i meant what i wrote: since the second directory differs from $PWD
only in the ".bak" suffix, `cd $PWD.bak` will have the desired effect.
