It's a process that's been in place long before I got here and it is done, with varying frequency, by the entire staff of developers here. It seemed a little odd to me at first also, but I was told only that it was faster than any other method. It might make a little more sense if you realize that it isn't a script, it's just me listing the commands that are used. This process is on /my/ (development) environment, so hasn't the potential to make bad days for anybody except me.
And, yeah, I suppose I could have gone with a "tar zxvf /path/to/file.tar" but I didn't expect OP was going to tar up his database first, so it seemed good enough for example purposes.
