I'm confused. Doesn't Onodera already know about "Yoshikawa" real gender?
I think it's just a lost translation there because I saw some panels with weird or misplaced translations. It's usually happened if you use machine translation (like G*o*o*g*l*e) because Japanese tend not to use a distinct word for gender: like Koibito for lovers can be translated as girlfriend or boyfriend if the listener know already what gender the speaker talked about.
And I'm sure the original text was written without the gender context, and that's how the machine translated into "she". (Maybe Onodera just said it without giving out a name or maybe he said "sensei" which didn't have a specific gender for that role)
Or maybe the translator just forget about this little fact because it happened far in the beginning which already a decades past XD
*Sorry for my bad English, I tried to explain it as clear as I could
