ECU with only two injecter driver? How come?

Hi guys,

Please look at the pinout diagram of my OBD2 ECU (P7G same as P71) driving my D15B engine.
It has only two outputs for injecters. One each for No. 1,4 and 2,3 respectively. Can someone explain how it works?

The wiring must be spliting up n going to both injectors.

Its just like that. I have varified it with my trusty old multimeter. But I always thought that all Honda MPFIs are sequential injection whereas this seem to be a batch kind of thing. Moreover, only one out of two cylinders must be in induction stroke at a time then what happens to the fuel of the other injecter?
