I would not have interpreted it that way. Actual text was "no luck reassembling" and I would normally assume only a part of the threading was damaged. Chasing it would be my first attempt and I've done that numerous times with reasonable success.
I've also had a thread that was re-chasable within a few millimeters of where needed --and actually used ball bearings that were one size larger to raise back into useful threads. (But that was a little weird and only done because existing parts HAD to be fixed)
