No, it is not false. The problem is that when you get up, and move around, your potential will change from that of the equipment. Touch it again, and you can have an ESD event. Ground the equipment and yourself (through a high value resistor) and it will ensure that everything will remain at the same potential no matter
There are different ways that ESD events can occur: the human body model is where a charged person discharged into a device at a lower potential, which is the most common, The charged device model, which is not as common but still equally valid, is where a device is charged through either contact with another charged object, or through tribocharging of itself. When this device contacts a surface of lower or ground potential, a discharge can occur and damage it. I've been working with ESD protection for more than 25 years, so, I'll keep doing what has been proven to work, has been scientifically accepted by the EOS/ESD Association, the electronics industry and the military. You're free to do what you want, of course.
