if you arte not fed up with the problem, please consider the following question.(adsbygoogle = window.adsbygoogle || []).push({});

A realistic approach considers the following scenario:

An unidimensional rectilinear (IN SPACE) path will be considered in which the moving clock starts its motion with zero initial velocity from the origin of the inertial reference frame I in which the rest clock denoted conventionally as (1) is located. After the velocity V is reached, the force F is instantaneously reversed. Then (2) is decelerated, stops and inverts its motion until the velocity -V is reached. At this point F is suddenly reversed again, so that, when (2) stops it meets (1) again and they compare their readings. [Found.Phys.Lett. 18 (2005) 1-19

I consider that after the two outgoing steps clock (2) is at rest in the rest frame of the stay at home clock and in front of a clock of that frame which reads (displays), as a result of the clock synchronization (Einsteinian) performed in that frame, the same time as clock (1) does. In short, the question is if we should consider the folloowing incoming steps? Is the statement of the clock paradox violated that way?
