Actually this is right, so the information in the article is somewhat incorrect. Thanks for spotting this! There is however an issue with the ActiveMQ implementation: once a user is assigned to a consumer, it is hard to make ActiveMQ rebalance it. At least by default the load-balancing does not take place until a consumer is dead. In case of a chat bot, some users may be returning, while others may quickly go away, leading to drastic imbalances. Apollo does the balancing perfectly out-of-the-box.
