The wibbily wobbily timey wimey nature of Hippolyte as Wonder Woman is such that it even contorts the language we must use for the event, thus the OP's rare tense construction and inordered spelling of the Amazon queen's name.

She should have been the original Wonder Woman given the time, but had not been the original Wonder Woman because for Hippolyte her daughter had already been Wonder Woman and she was leaving Themiscyra from the time after that happened to arrive at the time before. So she was the "legacy" character even though part of her adventures happened before Diana (in one timeline) had been Wonder Woman (and died) but after Hippolyte had taken up the Wonder Woman nom de guerre in the present day, inspired by her daughter and serving penance for her transgressions.

This is true but less confusing in the original original timeline where Hippolyte posed as Wonder Woman, after having used the time sphere to foresee a danger to her daughter, and came to Man's World disguised as the Amazing Amazon--"The Masquerader," SENSATION COMICS 26 (February 1944).
