Thanks for the explanation. So roughly speaking, the main difference is that in elementary backstroke, the hands never go past the shoulders, while in inverted breaststroke, hands extend long above head, correct? And in both cases both hands move together, rather than alternate (as in backstroke)?
It looks to me the elementary stroke would be best for survival since it saves energy and you face up without breathing problem?
That's correct in your summary, and, yes, the elementary backstroke is considered a survival stroke.
