Probably right. It's actually still normal/correct to draw a PNP circuit between negative rail and ground with the negative supply at the top. Schematics should convey how the engineer thinks about the circuit, and inputs come in the top and left and outputs exit at the bottom/right. Except no one really designs PNP-oriented circuits with negative supply voltages these days because eugh.
