First, a presumption: That the OSB wall shown for the second floor is insulated.
Now, what is missing is insulation extending from that second floor OSB wall down to the ceiling insulation in your photo.
I found that *all the time* and wrote it up *all the time*.
Just insulation installers *not thinking* ... wait ... no trade *thinks* anymore, do they?
The other way to have done it would have been to have installed the insulation on the garage ceiling at the floor of the second floor above ... but that takes "planning" and more "work".
