The TSA agent checking ID's does not have to check the CLEAR people. They simply glance only at the BP and not the ID. No need to scan the BP and compare ID with face.
The ID check and BP scan step is being done by a bunch of private people with CLEAR to help free up the TSA person.
So CLEAR folks allow the TSA agents to be more efficient at that step of the process.
If there were no CLEAR and all CLEAR people were Precheck, then the precheck line would take longer. Not much longer, but longer.
