Yes.... & no Saddlebag. Looking at the anatomy & way the joints line up, the hoof should *ideally* line up with the pastern. If it's not naturally like that though, while we might feel it's best to facilitate it becoming so with trimming, I don't think it's a good idea to enforce any paramater on a hoof with trimming. Eg. a clubbed hoof has a 'broken forward' pastern angle & while I don't think it *necessarily* should or shouldn't be changed, if it's deemed changeable, I wouldn't advocate the heels are just sheared off to do it - I think the approach needs to be more holistic than just trimming feet.
There's also the question of whether the dorsal wall is actually in line(parallel, firmly attached) with P3 too. For eg. one of OP's pics appears superficially to be a tiny bit 'broken forward', as you can see by the green line I drew, but I suspect that a lot of that wall is actually flared forward & the red line is more like the angle of P3 & hence pastern angle.
