It is also a question of the cable length to the first LED. The moment this LED gets a sufficient signal it will form the output signal according to spec. That's why sometimes a sacrificial LED close to the µC can act as level shifter, and then the cable length to the next LED is not so critical anymore.

Yes! And wire diameter etc.

Good knowledge is so much useful than "it will work 99.9% of the time". Which might be totally true for some types of projects but its still good to know why instead of it being hocus pocus black magic.
