Meaning of 「X 一緒なら Y 一緒」


> その高校とは昔から仲が悪くて学力のレベルも一緒なら評判や人気までも一緒

Is 「X 一緒なら Y 一緒」 a common structure? What is its meaning?

My attempt: "Relations with that high school have always been bad. From
scholastic ability to reputation and popularity."

Thanks for your help!




`A + も + B + なら/ば + X + も + Y + だ` is a pattern used to present two similar
facts in parallel. Here are relevant articles:

  * JGram: [も～ば～も](http://www.jgram.org/pages/viewOne.php?tagE=mo-ba-mo)
  * jtest4you: [Learn JLPT N2 Grammar: も～ば～も (mo~ba~mo)](http://japanesetest4you.com/flashcard/learn-jlpt-n2-grammar-%E3%82%82%EF%BD%9E%E3%81%B0%EF%BD%9E%E3%82%82-mobamo/)

In your example sentence, the "B" and "Y" parts happen to be the same na-
adjective, `同じ`. The speaker is saying two facts in parallel, "academic
abilities (of the two schools) are the same" and "reputation and popularity
(of the two schools) are the same".

なら is not always translated as "if". It can work as something like an emphatic
topic marker, similar to English "speaking of ～" or "regarding ～". Here's the
dictionary entry which is (probably) relevant:

>   * ［並助］《近世語》いくつかの事柄を並列して言うのに用いる。…といい、…といい。→なり［並助］
