It's not really confusing so long as you understand how PHP works. Each request
is brand new - nothing is retained from previous requests. The two variable
you're changing are set by PHP when the request comes in from the browser. The
fact you changed them in a previous request is irrelevant because 1) that
change was not communicated to the browser in any way, and 2) PHP doesn't
retain any data between requests [1].
If you've been coding assuming that changes you make to global variables are
retained between requests you must have been having some pretty frustrating
times!

Not really - this is the first time I've had something not work as expected.
