Correct ... and the more ports you activate (connect to splitters) the more loss you get in your CABLE TV and INTERNET service . Each additional port activated adds about 3DB to 5DB of loss depending on splitter quality, which (not counting cable and connectors which create loss as well) enough to make a difference. Exceeding 3 active ports could introduce TV issues on many channels, as well as internet issues. My loss doubled when I went from 2 to 3 ports active and when I added a 4th active port I had to add a amplifier so I used another method. My cable modem has a signal monitor and it's quite interesting to watch how every device and even coax quality affects signal. Adds up fast. I am sure new construction areas take this under consideration but down here the infrastructure is 14+ years old. There was a 4-way splitter (2 ports used) and I replaced it with a 2-way signal doubled.
