 The point with this scenario is that both twins are inertial
for most of the journey.
 I could obviously have calculated the result from the metric
like I have done with the scenario where twin B is accelerating
during the whole journey:

(Note that the simulation
   https://paulba.no/twins.html
gives exactly the same result)

This gives the same false result. It is as if we asked two students to give the result of 0.5c + 0.5c and both gave the same result Vo=c.
This does not make it a true result.
