The video doesn't provide enough context for people to understand what the argument actually is, which is basically the Non-Identity Problem.
The argument begins by assuming a premise that is fairly reasonable: the existence of any particular person depends directly on the specific chain of events that led to their conception. Even the smallest change in those events, for example, if their parents had never met, or even if their parents had had sex at a slightly different time, would result in a different person being conceived. In other words, that particular individual would never have existed; someone else would have existed instead. That's the premise that needs to be explained before introducing the example of the pregnant woman.
The point of the Non-Identity Problem is that, intuitively, we want to say that both cases presented in the video are morally wrong. However, the minimum criterion we usually use to judge an action as immoral is that it makes someone worse off. If an action doesn't negatively affect anyone, then most people would say it makes little sense to call it immoral.
The difficulty is that, under the premise we accepted, the child in the second case has not been made worse off by the mother's decision not to wait before conceiving. The reason is that the causal conditions required for that particular child to exist are inseparable from the conditions that result in the disability. If the mother had waited until her illness had gone away before conceiving, that child would never have existed. A numerically different child would have existed instead.
So the child's options are not "be born healthy" or "be born with a disability." Rather, the options are "be born with a disability" or "never exist at all." There is no possible world in which that same child is born without the disability, because the actions the mother would have had to take in order to have a healthy child are precisely the actions that would prevent that child from ever being conceived.
