Right different bike not the right pic's, that is an aftermarket cable.
I did some digging thru the manual.
There are no definitive pic's that show the Clutch Cable routing.
But there are several that show the cable and views where it runs and from the angles it takes in the pic's I can't see it running anyplace else.
I also found a few other pic's of bike with the cable run thru the frame.
I have it that way on (2) bikes and both allow full free movement of the bars with no change in the clutch feel.
This one has been in there for a long time.
The angle this takes has to go thru the frame.
Again thru the frame.
This is from theCB 175 Manual but the idea is identical.
From the CB 350 manual.
The bars are not in place but the Clutch Cable runs thru the frame
From this angle it has to run thru the hole above the coils.
Around the head tube to the right. the only way back is thru the frame above the coils.
Same
And thru the frame.
Maybe Steve can jump in.
