ASP.NET Identity 2.0 - Is the expiry timespan stored in the token & different sub-domains

Question

I have a verification token I'm using in a system (system 1). It is set to a 5 min timespan in the identityconfig.cs on the system that generates it:

manager.UserTokenProvider =
    new DataProtectorTokenProvider<ApplicationUser>(
        dataProtectionProvider.Create("ASP.NET Identity"))
    {
        TokenLifespan = TimeSpan.FromMinutes(5)
    };

My question is, does the TokenLifeSpan get stored in the token string itself?

The reason I ask is this token is handed off to another system (system 2). The same identityconfig.cs setting on that system uses a 7 day lifespan. I want my token to expire after 5 mins at the point of verification on system 2.

Generation Code - System 1:

string token_string = await UserManager.GenerateUserTokenAsync("MyPurpose", user_ID);

Verification Code - System 2:

var result = await UserManager.VerifyUserTokenAsync(user_ID, "MyPurpose", token_string);

In addition, it is worth noting: System 1 is on subdomain.mywebsitedomain.com System 2 is on www.mywebsitedomain.com

Will this allow the token to be passed between for verification? UPDATE: This will not allow the token to be passed from system 1 to 2..The reason is the 2 sites will sign the token with their own MachineKey. This can be explicitly set in the web.config of each site to allow the tokens to pass between sites.
