That is only guaranteed to work if subsequent tosses are independent of each other. TFA suggests that they are not.

[edit]

If you always start with the same side of the coin face-up, then the tosses will be independent of each other, but if you e.g. always flip it once or always keep it the same before the next toss, then they are not.

TFA does not suggest that. Even if a coin is biased towards the side it started on, this wouldn’t carry over from one flip to the next.

It would be important to start the flip on the same side, but that’s doesn’t make the second flip dependent on the first

Hah, realized that after I posted and edited while you were commenting. It's a good point. My original assumption would you'd just pick it up and flip it; not attempt to put the same side face up each time.
