Does my tie/fo still perform it even if it overlaps another ship?
S Loop question
I suspect it's a NO just like you don't flip over when your k-turn gets blocked.
Under Bearing in the Rules Reference:
If a ship overlaps another ship while executing
a Koiogran turn or a Segnor’s Loop, the ship
does not rotate 180º at the opposite end of the
template. The player places the ship using the
rear guides instead of the front guides.
Note that the colour of the maneuver still applies even if it didn't manage to complete the maneuever. So because the Segnor's Loop is a red maneuver for a TIE/fo, after you have resolved the overlap, you will still gain a stress token for executing a red maneuver.
Thank you
