No, it's saying that _in any moment_ you can only focus deeply on, and thus care for, one other person. And if you have to care for multiple people, then you have to shift your focus moment to moment.

As a parent, can confirm. To give an example, it's really hard to hold and comfort two crying kids at the same time. When the toddlers are melting, they really want your whole attention and don't want to share it. If they're melting because they got in a fight with each other, it really takes an adult per toddler to help calm them.

That doesn't mean I can't love and care deeply for both kids, it just means you can only implement that caring with one at a time.

I think he's generalizing the point a bit and not all situations are like that. But it's close enough to accurate to be valid. Care doesn't scale.
