Half siblings only share DNA from one parent. The genetic information from the other parent is different. Since both parents give us an equal amount of our DNA, it doesn't matter if two kids share mom's or dad's genetic information.
Either way, it's half. Some people may get confused about this stuff because of horse breeding. In the horse breeding industry, the term "half-brother" or "half-sister" only describes horses with the same dam mom but different sires dads. Those horses with the same sire dad but different dams mom are not called half-siblings. Instead horse breeders simply say that they are "by the same sire" with no sibling relationship implied. Even though this is how they refer to these horses, they are half siblings whether they share the same dam or sire.
Just like with people. People and horses and every other living thing use DNA as their basic unit of genetic information. It contains all of the instructions for making us.

So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test.
They would call you aunt or uncle, and your children would simply call them cousins… although of course, they are really second cousins. In some cultures, it can be looked down upon for cousins to marry cousins. There may be rules and laws against incest, due to genetic concerns.
In the United States, second cousins are legally allowed to marry in every state. Hilda, trembling at the door, more than half expected Mr. Orgreave to say: "You mean, she's invited herself.
