Not quite the same. Procedural drift is when SOP start to be amended by crews over time - either deliberately or otherwise - resulting in potential errors. e,g :
yes, when you are so used to doing something every sortie, like a hoist check, you can over-anticipate the other persons actions since it is an exchange of verbal confirmations and requests combined with a set of physical actions. The you get the switch pigs because one person is mixing the words and actions - usually accidentally.
I can't imagine they actually do the hoist check from a check list.
