you are right that the website and the implementation don't match, thanks for pointing that out. This was a feature request from a paying PyMOL sponsor, which often means that we put the feature only (or first) in Incentive PyMOL. But thinking about it, this is a rather small change and probably not worth to keep as a distinguishing feature. I'll port it to open-source today.
To clarify the issue with duplicated connect record. This is an unofficial PDB feature to store the bond order and is supported by several applications that read PDB files, but may break PDB file loading in other applications which don't support it. PyMOL always wrote duplicated connect records and the new setting allows you to switch that off.
