All Positions vs Defense on Defense strat cards

An all position offense strat card does not apply to the defense. It will however apply to offensive players in the specialist section(players not in your starting lineup). Hope that helps

All Positions may impact if offensive players are on special teams

I think my backup TE is on kickoff return

Or if your offense gets an INT, the Offensive players use their defense ratings

I would think so...can you equip one and compare? This would give you a definitive answer, but I would agree...they seem to be saying the same thing.
