i believe those injectors are used for the high rpm band. it allows the car to use lower injectors as the main injectors so that partial throttle and ideal can be consistent and run smooth. as opposed to running huge injectors only which makes the low rpm and partial throttle harder to tune correctly

It’s so the fuel atomizes properly before going into the ports at those elevate RPM’s the engine runs. Alot of race cars, some OE street cars, and some OE street bikes use this setup.
