Meh, overpasses are old fashioned (and still subject to transcription errors all the same). Current best practice is to never use 4-way junctions, except for crossings.
Which, the above circuit seems to take advantage of otherwise: the output is dog-legged from the
current sense B-E shorting wire, for instance. And then the capacitor and IN+ cross in an orderly fashion as we expect. But then Vcc goes into a damn current source, and all bets are off.
(Another reason against overpasses is the implication of orientation, ordering, or z-height, an irrelevant detail -- a minor one to be sure, but it does technically add to the visual noise. Conversely, one might argue the 3-way junction rule, harnesses visual noise instead: such connections tend to be less symmetrical, arguably uglier -- which highlights their importance, in a way.)
