Correct me if I’m wrong, please!

But in episode 3x15 - Eddie Begins, it shows that Eddie got shot on his left shoulder, right?

And in episode 4x13/4x14 - Suspicion/Survivors, it shows him getting shot on his right shoulder?!

Because I hear/saw a lot of people saying (especially in fics) that both gunshots were on the same shoulder, but that’s not what I saw.

Am I wrong and crazy here???
