Recording a script allows you to play back that script on your copy of Studio Pro. As your desktop computer will tend to have more RAM and resources in general, this means you can repaint your iPad work at the bigger sizes your computer will allow. So, you might have finished a painting on the iPad but you want to recreate it at a larger size. If you export the script file then open it in Studio Pro via File -> Play Script, you'll be prompted for the size to play back at. See the previous link for how to transfer files to your desktop computer.
