Not really true. If you have a full price / flex ticket you can take any train you want, and if you have a discounted ticket you are obliged to go to the info desk and they will give you a connection to take. They will also give you a new reservation. Connections do get missed, and if they do you are entitled to a 25% money back for 1 hour, and 50% for two hour delays.
