Just a thought from my limited experience flying: With a procedure which involves the two crew to do something in a set order (and is very thoroughly trained as such)....where one action or phrase triggers the next and so on.. if this flow gets broken or an incorrect phrase or type reversion occurs; both pilots can end up confused. Training for type conversion or initial type seems very much along the lines of 'flows' and set actions rather than really thinking just about what you want to achieve. Obviously the SOPs should be sat on top of basic airmanship and type knowledge rather than blindly following the procedure.. but time is money.
