This is dependant on another assumption: the mapping of the
translation layers between domains, and breaks at the translation
layer when the a' and b' lengths are zero. You need to take account
of the translation layers between coordinate systems.
Consider a domain X which contains a nested domain Y. Y has external
dimensions of 1x1x1 in X's coordinate system, but has internal
dimensions of 100x100x100 in Y's internal coordinate system. All 6
external faces of the cube formed by Y translate to surfaces in X.
Now take your stick of length 1. It starts in X's coordinate system
and moves in Y's. In Y's coordinate system it too has a length of 1,
however, as it crosses the border into Y, it instantly apparently
shrinks to a viewer in X due to the fact that its length now subtends
a tiny fraction of the visual angle that it did immediately prior to
crossing the border.
+--------------------------------------------+

| X domain Y domain |

| ...........+-----------------+ |
| ^ | ^ | |
| | | | | |
| | | | | |
| | 1 unit | | 100 units | |
| | | | | |
| | | | | |
| | | | | |
| V | V | |
| ...........+-----------------+ |
| |
| |
+--------------------------------------------+
The other approach is to define constant sized translation
interfaces, the base concept being that a translation interface must
occupy the same dimensional units in both coordinate systems. This
seems much closer to the TARDIS model, and also explains and allows
many of the cute multi-blob domain mappings.
+--------------------------------------------+
| \ External |
| \ interfaces of |
| X domain Y domain |

| ^ | \ | |

| V | / | |

+-----------------------------===------------+

#..... A interface |
# -B interface of length |
#..... of length 1 1 in Y |

| |
#..... |
# -D interface of length 1 in Y domain |
#..... |
| C interface |
| / of length 1 unit in Y domain |
| . . |
| . . |
| . . |
+--------===---------------------------------+
Further this allows the TARDIS-like mechanics of being in X, moving
south thru the B interface into Y, turning around 180 degrees and
exiting Y thru the D interface to find yourself facing in the same
dirction as when you started, and having traveled to the opposite side
of Y.

Except for the case when an object lies just other side of a
translation layer.
