This was the only way I knew how to display the step at which the build-setup process failed. I've personally experienced failures at multiple of the build steps, and before I got used to Chipyard, it was hard to figure out which step was the culprit. With this, users should have a bit more info to troubleshoot their issues. For some of the build steps that required multiple lines, I figured it made more sense to put them into a sub-script, rather than putting a && at the end of each line. But for the firesim one for example, since it was two .sh calls, I just put a && after the first one, inside of the try block, to make sure both lines run.
