According to current kicad sources, pin 1 should be to top right in both cases. This is indicated by the silkscreen circle on the current revision of the PCB in the kicad sources. Unsure if that's the same version you used.

If unsure, double-check the opposite pin (pin 5 = other side of IC and other end of IC) should have a via to GND.

Yes, both dots are upper right in that orientation.
