The page doesn't say that.

It says, "If you do not handle their respective change events, polling is not used." And, I have just added two words to that, 
"If you do not handle [any of] their respective change events, polling is not used." ([the addition])

I am not well-versed in how special devices are handled in Linux. But, I suspect that the kernel handles hardware interrupts 
while applications still need to poll the special device file descriptor to be informed of state changes.
