Did Chow Bak Tung and 1 Deng become a fighting "team" late in life?

Towards the end of ROCH, after Chow Bak Tung and South Emperor 1 Deng had amicably settled their decades-long "feud" over the Ying Goo affair, the two elder Greats had several occasions wherein they fought side-by-side (e.g. against the Golden Wheel Monk, against Mongolian troops, etc.). By that time, had Chow and 1 Deng become a pretty effective fighting "team?" They seemed to work very well together.

It's more of a shame from ZBT than feud with YD. YD had already forgiven ZBT back in LOCH.

As to fighting team, ZBT withdrew after YD joined the fight against JLFW. ZBT probably would be the worst teammate when it comes to fighting. He screwed GJ as well during the fight with OYF and QQR in LOCH.
