Not at all. What SR shows that there are relativistic situations in which 
it is impossible to establish simultaneous clock time t values, for 
relativistic observers to agree on the clock time t value of some event, 
and then ONLY in the case that relativistic frames are different. When the 
frames are relativistically mappable (no relative motion or acceleration) 
then t value simultaneity can always be established.

But none of that applies to the notion of the same present moment in which 
all these relativistic effects occur.

Clock time simultaneity is NOT the same as sharing the same present moment, 
as the different t values of the reuniting time travelers proves beyond a
