Both observers experience the exact same amount of light seconds.I dont understand the diagram etc. But i understand the heading -- Killing Time Dilation -- so i will comment.
There is no such thing as time, hencely no such thing as time dilation. Or, there is such a thing as time, it is the present instant, & this is universal, but it cant be dilated.
It would be ok to talk of ticking dilation, ie where processes are slowed by something, the slowing being due primarily to the speed of the clock etc relative to the aether. Here that V is inserted up Lorentz's equation for gamma.
Slowing in ticking might be exactly as described by Lorentz's gamma. But i doubt it. I thing that Lorentz's gamma might apply directly to micro ticking (eg atomic clocks), but i doubt that it can be applied directly to macro ticking.
Macro ticking is i think affected indirectly by Lorentz's gamma -- here gamma is merely applied to one or more dimensions of the macro process (the dimensions are contracted by LLC). Then the macro ticking changes according to whether it is a pendulum ticktock or a balance wheel ticktock or a tuning fork quartz ticktock etc.
Observers are of course just such a macro process.
I would think that the observer's tickerthalamus is a macro thing & has a complicated macro equation for ticking.
An observer ant would feel ticking & time differently to an observer elephant.
I think it depends on the distance from the eye to the tickerthalamus (with all due respect to the blind).
What kind of animals are your observers?
That was a major flaw in Einstein's train embankment lighting thortX -- he didnt cover the general case -- which would involve an elephant say in the carriage (the circus was coming to town) & an ant say on the embankment.
But there are three kinds of ticking, we have actual (absolute) ticking, & apparent (perceived) ticking, & relative apparent (perceived) ticking. Hencely it is easy to get into a fight here.
