The thing is, the first example doesn't handle many edge cases which normally arise and are a common source of bugs and security vulnerabilities. The second example doesn't suffer from those issues by design.
In other words, it's OK to type the first example on the command line and it'll work just fine (and if it won't, you'll be able to step in and fix). But running it as part of anything automated would be haphazard.
As I read this, the whole point is that you have something that feels quite familiar syntactically to a common shell, but sane. Kudos to the author!
