Possible to have different modem in same model? Whut?

Apple is using Qualcomm and Intel modems in this year's iPhone 7.

The Intel *does not* support CDMA, and the AT&T and T-Mobile models use the Intel modem (while the Sprint & Verizon model use the Qualcomm (which, ironically supports both GSM and CDMA)).

Now this article in Recode says:

By creating a separate version for Sprint and Verizon, Apple is able to use Qualcomm exclusively on that model while using chips from both Intel and Qualcomm for the GSM model used by AT&T and T-Mobile as well as many carriers in other parts of the world.​

I don't think this is accurate. This would mean that the GSM models (AT&T or T-Mobile here in the U.S.) could have an Intel modem or they could have a Qualcomm (ie, last year's TSMC/Samsung).
