"Failure to carry or produce any additional identification documents that may be required for entry into Canada or the US, i.e. passport.... etc"
So my take is that you run the risk of losing your NEXUS card if you were asked for your passport by US or Canada Customs and did not have it.
Basically it doesn't apply to air. That's the main reason. You are still required to be able to present a passport when traveling by air. In addition your Nexus card is NOT a visa document. If you have an H-1B or TN for instance, that is in your passport and not on your Nexus card meaning not having it with you is the same as not being able to produce employment authorization and as such you may be denied entry.

NEXUS and FAST membership cards will now be accepted as proof of identity and as documents that denote citizenship when entering Canada at all land and marine ports of entry. This means that citizens of Canada and the United States who are NEXUS or FAST members, and are carrying with them valid membership cards, are [b]no longer required to carry other supplementary documents such as passports or birth certificates with them when entering Canada by
boat or by land[b], when using non-NEXUS or non-FAST lanes.
Important note: The new policy concerning the use of the NEXUS card as proof of identity and documents that denote citizenship
does not pertain to the air mode of transportation. Members of the NEXUS program will still be required to carry the appropriate documentation when travelling by air.
