I really don't think so.
The bend must be the coil bend. Is that not the 'hook' end that is pointing up towards the camera?
Did you compare it directly against the new spring to see if the short, sharp angled hook bend at the end was the same, or as you seem to be saying, different, on both?
Edit: ok – I see your edit.
As for non-standard break, well it may be a bit of a lottery as to where exactly it breaks. The thing is that it broke in the section that is stressed when the coil binds. Often the other end of that section breaks – it is stretched more for the sharp bend – but I guess it could break at either bend (at either end of the short section).
I'd still be suspicious that it wasn't a loose enough fit around the boss, somehow there wasn't enough space to allow the full movement that that bit of wire is forced to make.
I'd be lookiing carefully at that boss again – size and shape.
On the other hand, maybe there are batches of bad springs with weak wire? ?
