Why not need to set Login url

I have downloaded the Portal Starter Kit from
http://www.ibuyspy.com/Default.aspx?tabindex=8&tabid=47
The authentication section of web.config is below
---
<authentication mode="Forms">
<forms name=".ASPXAUTH" protection="All" timeout="60" />
</authentication>
---
Why they didn't to set the loginUrl like this
<forms name="MyCookie" loginUrl="Login.aspx">
How does this application know the login page?It's likely that login.aspx is the default value when loginUrl is not
explicitely defined... The doc should perhaps mention this...
