It’s referring to the An-26 they had shot down just days earlier.

I still disagree. Perhaps you should read the English translation in this screenshot, which says they "just" shot down the aircraft. Again, this communication is dated 17-7-14, the same day as the shootdown.

Social media is an extremely poor place to go looking for 'proof' of anything, its second or third hand hearsay at best and deliberate misinformation at worst.

Anyone could have seen or heard about the plane going down over the war zone and posted about it on social media.
