Android application lifecycle issue. Finish() is not stopping the activity.

Here's an explanation of what I am doing in my application and what the output from adb shell dumpsys activity is. I am starting at the FriendsActivity.

Pressed the logout button, list of saved accounts now showing. Called using:

Intent i = new Intent("com.company.app.common.ACCOUNTS");
... put extras ...
startActivityForResult(i, 2);

dumpsys activity output:

Running activities (most recent first):
TaskRecord{44003ac8 #45 A com.company.app.friends}
    Run #6: HistoryRecord{43ffafd8 com.company.app/.common.AccountsActivity}

TaskRecord{43f679e0 #2 A com.android.launcher}
    Run #0: HistoryRecord{43f63640 com.android.launcher/com.android.launcher2.Launcher}

Chose an account to log into, the login activity shoes up with fields filled out.

Intent i = new Intent();
i.setClass(AccountsActivity.this, LoginActivity.class);
... put extras ...
startActivityForResult(i, 1);

dumpsys activity output:

    Run #0: HistoryRecord{43f63640 com.android.launcher/com.android.launcher2.Launcher}

Pressed the login button which runs:

Intent i = new Intent();
... put extras ...
setResult(RESULT_OK, i);
finish();

Returns to AccountsActivity onActivityResult:

if (requestCode == 1) {
    if (resultCode == 2) {
        ...
    } else {
        setResult(resultCode);
        finish();
    }
}

ACCOUNTSACTIVITY REMAINS RUNNING!

Choose an account again, back at login screen.

Press login button, returns to the Friends list as it should, but the activity stack is strange.

Press the back button, and the application closes. Hit the logout button again and the cycle repeats.

I have no idea what is going on and why this is happening. I did notice this in the last dump though:

Activities waiting for another to become visible:
TaskRecord{44003ac8 #45 A com.company.app.friends}
    Wait #1: HistoryRecord{43fdeee8 com.company.app/.common.AccountsActivity}
    Wait #0: HistoryRecord{43ec7840 com.company.app/.common.LoginActivity}

Activities waiting to finish:
TaskRecord{44003ac8 #45 A com.company.app.friends}
    Fin #1: HistoryRecord{43fdeee8 com.company.app/.common.AccountsActivity}
    Fin #0: HistoryRecord{43ec7840 com.company.app/.common.LoginActivity}

Very likely has something to do with this problem, but what does it mean?
