Yes
If you are standing on the south pole and look at the zenith you are looking at the SCP. Going any direction away from that is moving to less negative declination.
For me at latitude 29deg south, the SCP is 29 deg above the horizon. From that point (at -90 dec), if I move my scope say 10deg down it will be pointing at -80deg dec. The stars at that spot will move around the SCP with time and 12 hours later they will be 10deg above the SCP. As this shows it doesn't matter which direction you move away from the SCP it will still be moving to less negative dec.
