2 hets do what?

[kc261]

So it is with hets. They either are or are not. I think people use the 100% to indicate it is indeed an actual het while the 50% and 66% ones are still "coins up in the air yet to land" as it were.

Good analogy, except depending on who reads it, it might give the wrong impression. I think a slightly more accurate way of saying it is that phets are like coins that have landed, but no one has looked to see which side is up. The snake either is het or it isn't (the coin has landed), the issue is just that we have no way of knowing until we breed it to prove it out (look at the coin).
