From the script (emphasis mine):
Darth Vader strides purposefully down a Death Star corridor, flanked by Imperial stormtroopers.
VADER: Several fighters have broken off from the main group. Come with me!
Vader's wingman panics at the sight of the oncoming pirate starship and veers radically to one side, colliding with Vader's TIE fighter in the process. Vader's wingman crashes.
The debate is over. ;-)
It's perfectly logical! ;)
