COD 4 Modern Warfare Mission Question ?

Okay, I just got finished with the mission where you hunt down the Main Russians guys son who is the commander.....you have to chase him, he wears a blue jumpsuit. Okay well after I hunt him down and he kills himself on the rooftop......they show a video of his father the bald guy wanted revenge on the U.S. and U.K.......BUT DIDN'T I ALREADY KILL THAT BALD GUY 2 MISSIONS AGO WHEN I WAS A SNIPER IN CAMOFLAUGE??? unless it was a body double I sniped him in the head then shot down a helicopter, then hid for cover by the ferris wheel ?
