Languages and cultures are not 100% translatable. Words can mean one thing in one language in one area and something else elsewhere.
Simple example is the word Chutzpah, its doesnt translate exactly into english
or The following question Is Soda Kosher (Soda mean differnet things in different languages and difficult locations) It can mean Selter
We do not know how the question was asked of Rav Kanivesky and what the words meant to him and Gedolim always speak indirectly which is harder to translate
We are reading an approximate translation of an indirect statement making exact understand impossible
