Maybe that was worded poorly. A "Phantom Bloodsucker" is just like a regular Bloodsucker, except it has the ability to project phantoms of itself. So, quite often if the Phantom Bloodsucker (real) sees you first, it can project phantoms of itself to attack you, which is what happened here. Since I was in Pripyat, I was having phantoms of all types of mutants attacking me. When I noticed it was nothing but phantom Bloodsuckers in higher frequency, as my visibility meter went off, I knew a real Bloodsucker, who was projecting those phantoms and was about to attack me. I was trying to focus on the real Bloodsucker at the same time the phantoms were attacking me. That is what I was trying to describe, real ones and phantoms ones in the same attack, even though the Phantom Bloodsucker (real) was creating those phantoms. The screenshot is showing I'm being attacked by real and phantoms, even though we both know the real one is creating the phantoms. There are also regular Karliks and Phantom Karliks.
