I took a look at the video and supporting files. It appears to me that the video was meant to be a "demo", and not actually document the steps for a "Hands On" exercise.
The "Hands-on" steps are documented in the "Output.pdf" file contained in the "day2_project_files.zip" file.
One thing to note as well, there appears to be a typo in the "Output.pdf" file, Step 5 and 6 (on page 1) reference incorrect path and file names. You will want to use the "LiveCycle in a Week (Output ES2).lca" found in the root of the "LC Output" folder (found in the "day2_project_files.zip" file)
Hope this helps.
