No, Marion, sorry. One is the complete Orchestra score, flute, horn, etc. and the other is the first page only of the violin/piano arrangement. I'm glad you posted the answer, I now have vague memories of being told that, and physics wise, it makes sense.

When you touch the high harmonic A, you have "stopped" the string--i.e. shortened the vibrating length. You basically now have a new string length. So, to get a different note you must stop the "new" string below the fist stop.......I'll have to go try it in a bit.

Here is the orchestra score, and here is the violin/piano. This one is only the first page, you have to pay to get the whole thing. You will probably get a blank screen. Just click on the screen, and it will download something called "Sibieus" so you can see the score. I did, and my computer seems fine. It's also free.

I couldn't get it to print any way I tried, though.
