H&S III strcat() wrong?

I just received my copy of the 3rd edition of "C: A Reference Manual" by
Harbison and Steele. They state that the strcat() function can be implemented
as:
char *
strcat(char *s1, const char *s2)
{
s1 += strlen(s1);
strcpy(s1, s2);
return s1;
}
Since the return value does not point to the beginning of the original s1, is
this implementation standard-conforming?
(BTW, in the ~50 pages I read of H&S III last night, I found lots of blatant
typographical errors, some of them in the function prototypes for standard
library functions. I'm returning the book to Prentice-Hall and letting them
know that their quality needs heavy improvement. Does anybody actually
proofread technical books before publishing them anymore?)
