This story would be partly correct if you were using the ancient coax solution which is a shared medium, which UTP is not (each cable is just for communication between 2 devices). The 100 meter maximum for UTP is based on the signal quality that's left after 100 meters... Maybe someone else whose native language is English can explain better...
