Let’s parse this a bit as I think there are two important qualifiers:
Nationals of Canada and USA with a NEXUS Card embarking in Canada in a non-USCBP pre-cleared flight must clear US immigration via the normal inspection lines. The use of Global Entry kiosk is not possible.
Nationals of Canada and USA with a NEXUS Card embarking in Canada in a non-USCBP pre-cleared flight must clear US immigration via the normal inspection lines. The use of Global Entry kiosk is not possible.
My conclusion is this: Your usage of the Global Entry kiosks in the USA is tied to your passport or green card. That is, you have to put your passport or green card into the GE kiosk and not your GE card (and certainly not your NEXUS card).
Timatic is trying to warn you that if you travel with just your Nexus card and no passport from Canada to the USA in a non-pre-cleared flight, you won’t be able to use a global entry kiosk as it doesn’t read nexus cards or even global entry cards (only passports and green cards).
APC kiosks are "Automated PASSPORT Kiosks" and only take passports although some but not all take green cards.
tldr: You’ll have to get in line and show your nexus card to a physical agent.
