What? No. The missing piece should be one section.

I'm saying screw through the far joist into a horizontal block perpendicular to and aligned to the top of the far joist in the small bay against the wall. Make that block longer than the width of the hole so you can also screw down through the subfloor into the block at the ends. That will be enough to support the subfloor in the narrow bay against the wall if someone steps there for some unlikely reason.

Then you should also block along the seems in the center bay so the missing piece of plywood has support under the break. Just regular vertical blocks. It's called "boxing out."

You would do the same for like an attic access hatch, so there is support along every seem. You don't need to bother with the one inch gap between the double joist and the next one, that's too small a space to deform even if someone leaned on the exact spot with a cane or something.
