ReSharper Warning - Access to Modified Closure

I have the following code:

string acctStatus = account.AccountStatus.ToString();
if (!SettableStatuses().Any(status => status == acctStatus))
    acctStatus = ACCOUNTSTATUS.Pending.ToString();

Note that account.AccountStatus is an enum of type ACCOUNTSTATUS. On the second line, ReSharper is giving me the warning "Access to Modified Closure" for acctStatus. When I do the recommended operation, Copy to local variable, it modifies the code to the following:

string acctStatus = realAccount.AccountStatus.ToString();
string s = acctStatus;
if (!SettableStatuses().Any(status => status == s))
    acctStatus = ACCOUNTSTATUS.Pending.ToString();

Why is this better or preferable to what I had originally?

EDIT

It also recommends Wrap local variable in array, which produces:

string[] acctStatus = {realAccount.AccountStatus.ToString()};
if (!SettableStatuses().Any(status => status == acctStatus[0]))
    acctStatus[0] = ACCOUNTSTATUS.Pending.ToString();

This seems downright wacky to me.
