#2I was surprised that this could happen, then I thought how frequently does this happen. Any other examples y'all are aware of?

Other possibility: Ios allows you to register a second face to unlock the device through face id. Could it be that they registered their face on the device?

No, that was suggested but apparently they haven't done this.

#5How old is older? - faceid can have issues with young siblings, and of course identical twins.

Boy is 13, his sister is 17. They have different noses.

#9It lets you register an “alternate appearance”, could that be what is being used?

#10Not rare. Approximately 80% of people have a brother or sister. On average siblings are less than three years apart, and share 50% of their genes. Children from the same parents tend to look alike.
Apple has researched this:
> The probability that a random person in the population could look at your iPhone X and unlock it using Face ID is approximately 1 in 1,000,000 (versus 1 in 50,000 for Touch ID). […] The probability of a false match is different for twins and siblings that look like you as well as among children under the age of 13, because their distinct facial features may not have fully developed.
