this wasn't my diagram, but looks actually correct.

My own explanation for the so called twin paradox was a bit similar, but 
based on the idea, that acceleration causes the relativistic effects and 
not velocity.

Such a travel would cause a situation, where a spaceship gets 
accelerated from - say- Earth, to reach a certain travel velocity to a 
distant star and a planet there.

Then the spaceship gets decelerated in order to land there.

Then the spaceship starts from there, travels back to Earth and needs to 
decelerate here.

This requires four instances of acceleration (two positive and two 
negative), which should cancel the effect.
