Question about Avant Que

Hi Ry,

Avant que always takes the subjunctive, whether there is a change in subject or not. Note, that this isn't in contradiction to your rules.

I was taught at school that Avant que takes subjunctive only when there is a change of subject. 

This is also confirmed here:

However, it seems that in the examples on this website, Avant que always takes the subjunctive, regardless of whether there is a change in subject. 

For example: Avant que je n'aille chez Paula, je dois acheter des fleurs.

(Before I go to Paula's, I have to get some flowers)

I have the same question.
