Your second call to header() uses the same header name, thus that header
(Location) is replaced with http://someplaceelse.com. The code works as
expected.
If you expected your conditional statement to fail, you are probably confusing
headers_sent() to mean something like have_i_used_the_header_function_yet().
The headers are all sent at once, regardless of how many times you use
header(). This function helps people avoid receiving the headers already sent
warning, and as long as you have no output yet in your script, you should still
be able to make changes to the headers.
Hope that helps.
