Good explanation.

This has the interesting implication that the relative speed between the portals is "added" to whatever goes through it.

Example: the blue portal is on a train running with the same speed in opposite direction. The people-bundle would instantaneously be accelerated to twice the speed of each of the trains. (This becomes a real headscratcher if you were able to put the portals in a particle accelerator)
