It will be the case as long as the $_POST, $_GET and $_REQUEST superglobals
are defined as associative arrays, where the last key overwrites previous
ones when equally named.

On the other hand, I think it's not a good idea to base your solution on
this behaviour, because it may be subject to future changes.

A more reliable way of seeing on which pages your visitor has been is to use
sessions.
