Because, the timer is raising an event on the server side. The way ASP.Net
works is the client requests a page from the server, the server receives the
request, parses the server-side content, executes the code-behind and
server-side code, then returns the results (usually in the form of a web
page [html]) back to the client machine.

The page and execution of the code is complete, probably before the timer
elapses the first time.

HTH, maybe someone else can explain it better than I.
