No it doesn't, the secure enclave is a separate chip, it doesn't uses ARM trustzone, infact AFAIK Apple never implemented trustzone in any of their SOC's.
Considering the previous publications by this author the issue is most likely within the TZ Kernel that QM uses not in the hardware itself, previous vulnerabilities that were disclosed by the same guy/gal/singular or plural sentient entity were patched.
To be clear, Secure Enclave is a coprocessor on Apple's A7 and later SoCs, it's not a physically separate chip from the main processor. But you are correct it's different from TrustZone.
Early, iOS 7-era articles on the ARM chips used in the 5S imply Apple based their work on TrustZone, do we have any citations to definitively say either way? I suppose all this speculation will have to wait until more details are released or discovered.
