It is, but if you look back to 2002, you will find that the 2002 WRX was the first Subaru B-pillar to thwart the jaws of life. Special techniques were developed for new Subaru vehicles within 6 months. It involved cutting to either side of the b-pillar, and detaching the roof from that structure. It was the diagrams distributed with the new rescue procedures that actually exposed the roll structure Subaru utilized.
Look at pictures of rolled WRXs, STIs, Forresters, and Legacys. You will see that even with the roof peeled back, the roll hoop is still in place. Many examples, the roof itself will peel back in the accident, but the hoop will still be there.
possibilities:
1) The jaws of life have become substantially beefier in the last 10 years.
2) Toyota roll structure isn't as beefy as Subarus. The Subaru hoop would lead to more weight up high in the car, and be detrimental to the low CoG target.
3) The picture isn't clear enough, and I'm fretting over nothing.
Only antibiotics at the moment.
The A-pillar is irrelevant, as it isn't nearly as reinforced as the B-pillar on Subarus. The jaws of life will cut through A-pillars of a Subaru without issue.
EDIT: Most of the old articles are gone or paywalled now. Looks like some cutters are catching up to Subaru and BMW.
