Because the FUA commands do not affect the internal queuing or

transfers can still be cached, they just can't be signaled complete
until the command is written to disk.
I'm relieved to hear your assurance that there is no data integrity problem. I'm still worried about adding extra complexity to the drives and the possibility of confusion.
What are the benefits of FUA? Do the benefits of FUA justify the risks ? Will drive hardware need to change ? Does FUA apply to Reads ?
