Anything you are seeing at ground level is old damage. It takes 9-12 months for a hoof capsule to grow out entirely from coronary band to the ground.
Toes are way out ahead of where they need to be again, unfortunately. Agree with you that it looks like something triggered another episode in the last month or two, as you can can see by the steep change in the angle of the 1" of new growth just below the coronary band.
Need to get aggressive with backing those toes again.
