There are a few errors in the Electronix Corp reverse-engineered schematic, unfortunately.
That's one of them. Another is the connector to the reset switch and power LED.

Here's a corrected copy—I could have missed some more errors, though.

39 downloads of ver 2017-8-27.
changes:
2017-8-27 : nets on PPU pins 18, 13; cartridge connector pins 37, 65; reset button/power LED daughterboard pinout
2017-8-28 : net on PPU pin 21 (/WR) - connected to wrong net
