PH Hypo does mean possible het for hypo. It could be that the breeding that produced the Enchi was between an Enchi and another snake and one of them may have been 100% Het for Hypo (Ghost) but there is no way to know if the gene was passed until you try to prove it out. That would be easiest done by eventually breeding the new snake with a Hypo female and seeing if any Hypos are produced. Even if it is het for hypo, it could take a couple clutches to prove out. Enchi is a codominant gene, not recessive, so the offspring you could produce may be Normal, YB, Enchi, or Enchi YB and until you prove out the Hypo I wouldn't even worry about the possibility of het for hypo in you clutch.
I agree with the poster below you that you should learn more about breeding before jumping into it, but my concern is not that you aren't clear on the genetics. (It may be helpful to the poster below you to brush up a little on genetics as well) My concern would be that it sounds like you went to a show, bought a snake, brought it home and put it with your animal without any quarentine period, what so ever. If that is not the case then forgive my presumption. If that is what you have done and the snake you purchased is carrying a disease or something lethal, what you may produce will not be an issue, as you may not have any animals left to work with. That is not responsible ownership. The number one rule of BP ownership; Always quarentine a new animal away from your collection for a period of 60 to 90 days minimum.
It's too late now to undo anything, but you may still want to look at some of the basic caresheets on this sight and sharpen up on egg incubation and hatchling care, before you need to know. Though it may be the case in some research processes, failure is not the best way to learn where living animals are concerned.
