Hi Jason,
Here's an "article" I recently wrote that might help:
http://www.codeconscious.com/rebol/articles/rebol-concepts.html
Warning though, it has not been critiqued in any way.

My answer would be that each time you enter a [] at the console, Rebol will
recognise the string form of a block and create one in memory - so you get
multiple - one each time you do it. Within a script however, Rebol will
recognise the form of the block once (when the script is loaded) and thus
create the block in memory once. I don't know if this is *exactly* right but
it seems like it could be close enough.
Regards,
Brett.
