WTRIS and rudder question

1. During normal flight with A&B hydraulic available all turns are done without rudder assistance, as flight spoiler counteracts aileron adverse yaw. TRUE or FALSE?

2. During manual reversion (no A & B hydraulic to flight controls) standby rudder pcu is powered and WTRIS is functioning to assist in turns as there is a possibility flight spoilers will not operate to assist in the turn due to loss of hydraulic power. TRUE or FALSE

So if 1. is false, then why is there no WTRIS during normal flight (sys A & B available) for turn coordination, as there is no command to rudder other than yaw damper and manual inputs.
