What is multi port direct injection? Surely it's one or the other?

The FRS uses 1direct injector and 1 port injector per cylinder, the direct injector has a specific spray pattern.

On the other hand, mazda skyactive uses 1 direct injector to feed 6 ports of fuel per cylinder. They claim its not a spray pattern, more like small multi-spray tubes.
