I've never seen this one. What does it do?
Some sort of automatic editing of sources.list?

It's a shorthand way of executing two commands from one command line. The second command will only execute if the first command is successful (returns an exit status of zero). Here's a short test you can try:

$ false && echo First command was successful
$ true && echo First command was successful
First command was successful
