was breathing是错误的吧（没有主语啊）

问题描述

Other outlets have said he had suffered several strokes, was breathing with the assistance of a ventilator and had only a 50-50 chance of recovery.

感觉这个 was 是多余的，没有主语啊？

老师答疑

刘老师：

...he had suffered several strokes, was breathing with the assistance of a ventilator and had only a 50-50 chance of recovery. —— had suffered, was breathing and had：3个并列的谓语，主语是he。
