Split takes a line as input and makes an array according to the split regex. The split regex defines what constitutes a new array element boundary. During the split process the "separators" are "consumed", meaning deleted.
The regex above says: "if I see one or more, spaces, colons or left paren or right paren", delete those and move what is left over to the left as an array element. This part: [6,7,8,-2] says ok, I've lots of stuff but I only want the 7th,8th,9th thing and the 2nd one from the end. Perl arrays are indexed at zero. So the first one is index[0]. Run my "hint" code and see what happens if you delete () from the regex. Experimentation is key. Run some examples and report back.
This is not a perfect analogy, but if you had an old style typewriter and hit "carriage return" every time you saw the matching regex, you would wind up with my "hint" code.
