For Step 1 purpose, you're right they're essentially the same. People often use them interchangeably. If you care, read on,

In the research community, they are different. Pre-mRNA is a specific type of hnRNA. hnRNA destine to be processed into mRNA and exit to the cytoplasm is named pre-mRNA. Other hnRNA stay in the nucleus to be degraded or perform other functions within the nucleus is still named hnRNA ( I'm not too clear on specific functions of these.) So in a sense, all pre-mRNA are hnRNA, but not all hnRNA are pre-mRNA.

@MEDICINE DOC, sorry I didn't see your reply. I didn't mean to skip-over your comment. I must have been composing my answer when you're posting your comment.
