Locking the steering wheel straight-ahead helps protect the air bag clock spring that runs through the steering column. The clock spring maintains electrical circuits for the airbag and steering wheel controls while the wheel turns. If you disconnect the column with the wheel in a turned position, that twisting load can over-stress or snap the clock spring’s windings and contacts, risking loss of airbag deployment, horn function, or other controls. Keeping the wheel straight minimizes that twist and keeps the clock spring near its neutral position during service. The other choices don’t address the real risk here: sensor alignment or reassembly ease aren’t the primary concern, and battery drain isn’t affected by disconnecting the column.
