If the loads at the end of each leg of the star are considered lumped,
which they should be if the star legs are short enough, and with series

And further writes:

With receivers becoming drivers, the termination isn't series source. Can
this work, or does it work because 2 stub lengths from each driver to
each receiver is still short enough such that reflections occur while the
signal is still transitioning, thereby preventing overshoot?
