Yes it is out of position.
Compare with "Figure 5 - Typing Unit" on Page 8 SECTION 574-122-702TC.
You can see the correct position in the FORM-OUT MECHANISM area.
The contacts are the INTERLOCK CONTACTS used for stopping the papertape
reader while doing a formfeed. (Only used in sprocket feed assemblies).

You can get a pdf file from my website showing the wiring diagram for an
ASR33. This IMHO gives the best overview about the Molex connectors.
It is located at
