The carry flag is set to zero for these logical operations. These operations do not carry, nor do they borrow.

Paging through the 8080/8085 Assembly Language Programming Manual from Intel (© 1978), I can not find any explanation other than that.

Would you know it. Someone actually scanned this book and put it online. See here. I actually have this book, but the the pdf will make it easier to add the image shown below. This was taken from page 1-10. (Click on image for better view.)
