The thing is, on the next action switch
print_r($_COOKIE);
returns empty until I refresh the browser. So, thusly, the second page load brings in the cookies.
$_COOKIES is a convenient array that contains the contents of the Cookie header, nicely parsed.
Whenever you set a cookie, you're really adding a Set-Cookie header to the response. Thus, the browser has no way of knowing your intent until it receives the response. This data won't be in $_COOKIES until a subsequent request is made in which that cookie is included in the Cookie request header.
This chapter of HTTP Developer's Handbook explains cookies:

See Figure 11.3 for an illustration of the exchange I just described.
Hope that helps.
