Questions about notation

[FlatPanda]

I have searched around in the forum, but didn't find a topic, which would be a general discussion about music notation in general (especially outside of PGS), thus I'm starting this. And starting it with a question

I have came across the following notation in an arrangement of Polinaise op. 53 Héroïque by Chopin:

It's still way outside of my comfort zone, but I'm still interested, how this should be played out. The obvious part is that the measure with the Volta "1." should be played on the first run, the measure with the Volta "2." should be played instead, when repeating. But: the piece ends with a "D. C. al Fine", thus starting from the beginning until Fine, which is the same measure with the Volta "2.".

The question: when playing "D. C. al Fine" does one play both measures or only that with the Volta "2."?

Good question. I would think that since 1 and 2 measures are musically in the same place, you'd play the 2 without the 1 the next time through. Also, that is where the fine is. But this isn't something I've thought about much before.
