quaternion algebra: possible error on proof

Question

I am reading this proof and I don't understand whether the highlighted term in second and third step is a typo or I am missing something. I would expect it to be

$$qpq^*$$

Thanks for the help!

In the next line, where it says "by bilinearity", it certainly seems that it's being used as if it were $qpq^*$. — saulspatz, Jul 20 '19 at 13:09

Well, it should be $qpq^* + (qpq^*)^*$.
