Absolutely is true. Those networked computers are NOT writing directly to your SD card... the computer it's mounted to is doing it, exactly the same as in the FTP case mentioned above.
Where he says "direct" access is the key factor. Only the machine it's mounted to can write to it. As most Android devices can't join your network and share the SD card as a network drive, you have to unmount it from the Android device and mount it to the PC first. The PC can share it as a network drive, so the other PCs on your network simply tell the one PC it's mounted to what to write. But, that doesn't change the fact that one and only one device has control over the SD card, and that's the one it's mounted to.
