NO...the light path length of the observer's rod is assumed to be t*c where
t is the transit time from one end of the rod to the other end. The observer
will determine the light path length of an identical moving rod using IRT as
follows:
A is the observer and B is the observed frame:
Lba=Laa(Faa/Fab) or Lba=Laa(Fab/Faa)
Laa=the light path length of the observer's rod in A's frame as measured by
A.
Lba=the light path length of an identical rod in B's frame as predicted by
A.
Faa=the mean frequency of a standard light source in A's frame as measured
by A.
Fab=the mean frequency of an identical standard light source in B's frame as
measured by A.

No that's the point....the speed of light is isotropic due to the structure
of the ether. For a description of such an ether please read the following

What is the purpose of synchronizing two clocks in the same frame? I don't
like using light to synchronize clocks. i like slow clock transport of two
touching and synchronized clocks in the opposite directions. SR says that
such a pair of clcoks will remain synchronized.

Exactly....in Einstein's train gedanken the light strike simultaneouslywhen
both observers are at equal distance from the strikes. The track observ will
see the strikes to be simultaneous at L/c. According to the track observer
the train observer will see the strikes to be simultaneous at gamma*L/c.
