regex

I spent like three hours trying to understant how does "(?<!^)(?=[A-Z])" works to split at tring according to capital letters i.e.

string[] s = Regex.Split("TheWorldWithoutStrangers", "(?<!^)(?=[A-Z])");

How does it work !! I do understand what is the meaning of each char in the above expression, but I do not get how does it work together. why "(? < !^)([A-Z])" doesnot work ? it means that whenever you find a captial letter that is not after a new line, then split, am I right ?
