The misleading documentation that started all the controversy was about Heroku's legacy Bamboo stack, not the new Cedar stack.

The Cedar stack (which Heroku has been encouraging people to use for a long while now) has always claimed to do random routing.

This isn't true. Their main "how it works" page claimed intelligent routing with no mention of which stack. This has been changed since the uproar. There are other places the same.

This is only part of the whole story as well.
