Ok, to be honest, Im doing some work on the Z and I accidentally drained the battery the other day, so it probably needs a window reset...lol
Now this post has me curious.....

But Ill do that later and let you know what I find. BUT I do know that the DS does have the two switch positions for the PS, Ill confirm auto up from the DS and confirm number of positions on PS and if one or both have auto up for the PS window

This may be an EU or newer model thing. My 2009 would auto-up the passenger window.

It is possible that your passenger window switch isn't working properly. The passenger window switch has exactly the same two positions (Manual UP and Auto UP) as the driver window switch. At least, this is the case on my US 2011.

Although perhaps it is possible the EU and US models have a different passenger window switch.

Its not just my switch its everyones in the UK and perhaps EU.

Seems like the USA passenger window switches are not nobbled.

If you follow my link in my earlier post you can see how Nissan disabled auto close for the passenger window.

I confirmed that both the DS and PS window switches both have 2 positions, and both do auto up. Yeah, its an EU thing I guess.

Tested mine..Works fine..I thinks it's an EU problem
