Yes, I know that, but in the situation I described I had journaled the results and then closed the report window. To go back a recreate the report window would have taken a lot of time, as it contained 50 different non-linear model fits in a customized report window I created with JSL, and I couldn't just "save script" and rerun the script for all of those results, as for each non-linear fit you have to go in, check the results, modify starting conditions or paramter bounds, and do extra work to get a good fit in many situations.
Additionally, I can come up with a number other reasons that I'd want to share a Journal in JMP Live:
1) simplicity of layout:
Compare these two layouts of JMP results. The one on the left is the report window, the one on the right is a Journal that I have rearranged the output into a more "rectangular" and wider view. Most displays are wide, not tall, and JMP reports tend to be tall, not wide. In addition, I've change the order of some of the content and deleted things that I don't want to show.
2) many people use Journals to help with standardized workflows
3) Journals are easy to edit and modify with using JSL
