Who's correct? Manual or Google?

It's been bothering me a bit and I need to get it off my chest. What's with the wiring diagram in the manual for the 140ST? The polarity is reversed from what we have here. Is my whole house and my neighbours whole houses wired incorrectly or is the polarity different from the US outlets vs the Canadians. Probably the same electrician did both houses. Very common back in the day, I hear.

My stove is 240v (NEMA 14-60) with 120v accessories so it's wired for 120v internally from the factory (Neutral for 120v). I assume it's correct and to code but still the polarity is opposite from what's in the manual. Maybe the 240v wiring in the house is to blame for this. The house is old too. That really doesn't excuse all the sites I've researched that says common/neutral/white wire goes to the large spade. Maybe google and all the sites available to me in the western world are incorrect.

Am I just seeing things or is there come conspiracy to keep me in the dark about outlet wiring!? Has anybody had these issues?

PS: I'm running on 240v anyways so polarity is not an issue but I'm too lazy to carry a multimeter with me to check every outlet before I hook up. Plus I don't have room in my carrying case for one.
