"Your confusion about checklists on ground may come from the fact that in older SOPs, only the CMD started engines, taxied and took off. This is no longer the case."
Funny this,
After 20 years of PF doing everything (F/O doing starts , rejected take offs, you name it), we just changed back to the Boeing way of doing things. This is: Captain starts engines , calls for on block checklists, rejects take off etc.
This is met with considerable resistance in one particular division, and silent acceptance in others.
It all boils down to Company SOP's, and they may be considerably different from factory SOP's. They all work, just go with the flow.
