Sounds like OP's flight was domestic, which explains the pre registration part.

as a CLEAR/Global Entry user, and having both my passports scanned into the United system, this makes logical sense to bake into the end to end travel process.
The CLEAR system works well, although sometimes the (IAH terminal C) GS line is quicker...
if regular TSA could add it too...
interesting that you have to take your mask off... I though biometric was Retna scan (with CLEAR) while the SITA method sounds like facial recognition... which makes sense if they’re going off DL/passport photos
