Quoted from Shanghai Disneyland's actual website:
"If you see a long line at an attraction and prefer to come back at a designated time with a shorter line, you can! Pick up a Disney Fastpass ticket—available at participating Guest Services locations for no extra charge."
The description of how to use FP then goes on to explain the system, which is essentially the same as Disneyland's system bar the fact you have to get FP at a Guest Services location in the land of that particular attraction
I think it was probably either a mis-translation by the author of the article or a mis-understanding on their part
