No, not really...
Many textbooks about relativity use the picture of a train with one observer on the banks of the track and one within the train.
These observers are usually placed in the middle between two simultaneous events at both ends of the train.
Now the man on the bank has kind of special mirror, which allow him to see both flashes at the same time.
Then relativity of simultaneity is explained as different observations on the bank and in the train.
But I would require to remove the delay, caused by the finite speed of light, what would make both observations equal.
And as far as I call tell, Einstein used the picture from above, because he made no attempts to remove the delay.
His concept would allow to synchronize clocks, too, but only two clocks at a time.
In contrast I would use a different concept and use a hypothetical signal with infinite velocity to define simultaneity.
To make light usuable I would measure the delay and add that to the observed time value (seen at the remote clock).
This would allow a time measure, which is valid for the entire frame of reference.
