They were following standard procedures here for going around and not improvising. Standard procedure is to climb out runway headings usually and then make some turn. In the same way, the pilots would have seen with their eyes before the minimums threshold that the runway was not clear and made the go-around decision. It's not a great situation but I don't think it was that dangerous ultimately.
And it's press button, receive go-around. I would imagine that choosing to hand-fly in that scenario would usually produce worse outcomes.
That close to the ground, maybe it is not safe to attempt sudden horizontal changes?
Any kind of turn costs lift, and that’s not what you want to spend when you’re trying not to hit something on the ground. As such turns are generally not performed below a certain altitude.
