why this return?

Hello,
what's the point of having something like this:
(This code was copied from a book)
What I don't understand is: why is there a return type and a return if we are changing the variable (since it's memory reference is passed to the function).
Changing that to void (no return) does the same thing.
Why is the first one better?
Thanks.

char * strcat ( char *dest, char *orig ) {
int i, len;
for (i=0,len=strlen(dest);orig[i]!='\0' ;i++,len++) {
dest[len] = orig[i];
}
dest[len] = '\0';
return dest;
