That's because the example in the  "Rolling Ships" was written for
Cinematic movement, not for Vector. That rule can be used in both
movement systems (which is why it is under the main header "New Fire
Arc Rules" <G>).

Cinematic is the original system (and therefore standard, from the
rules' perspective) while Vector is purely optional. Don't expect the
examples in all optional rules to take all other optional rules into
account, like :-/

It does not apply to PDS and C1s used in PD mode. Same reason as why
PDAF and ADAF were allowed to fire through the rear arc at all in FT2
while beams were not: game balance.

If you want a PSB explanation, assume that fighters and missiles make
an attack run from the position of their marker to their target ship
and that PD fire takes place at ranges far, far shorter than 1 mu.
Ships, OTOH, are  assumed to be at the position their model (or the
center of the base of their model, to be more exact) is, and long-range
fire control is worse affected tha point-blank ones.
