the second thing happend and he lost
it.
was meant to imply that
both
things made him angry and combined
together he decided to ‘divorce’ his
pilegesh so they are both true
That is actually the basic Pshat in the Gemara. In a deeper look, there is a Machlokes and Svaros Hamachlokes, and the metzius was just like the Machlokes. There are two angles to approach the cause. There was disgust and danger of harm. Each was an important element.
In fact, it’s not simply a Machlokes of which one, that the true answer is, both. The actual story has two ways of looking at it. Was it mainly the aspect of disgust that allowed him to agry over anything, or, although he was disgusted he actually got angry over the danger of harm. The Machlokes remains, which element is really the cause, while the other is insignificant.
