Manual TDC sub sim video

Hello guys,

I'm trying to learn how to use manual TDC. I have read all kind of tutoriasl and get some idea what iANGLE ON BOW actually is. As the reference I'm using a picture posted on this forum while ago

Now I'm watching a subsim video about use of manual TDC and trying to understand how AoB was calculated.

Tear me to pieces, but I don't understand why on the video angle on bow is 129 degrees!

1) Enemy ship moving right to left
2) Sub pointer toward the enemy ship at the angle
3) Relative bearing to the ship is 340 degrees
4) Based on my understanding AoB should (between the enemy ship course and line of sight from the sub) should be less than 90 degrees on a port side!

What am I missing?
