FutureSignal refresh() and reload() AsyncLoading status change does not match the API description

[lux-ok]

I'm not sure if I understand this correctly. According to the instructions, refresh() maintains the state and only changes isLoading, so it shouldn't enter AsyncLoading. However, in my test code, both refresh and reload enter AsyncLoading, which is inconsistent with the instructions on the website https://dartsignals.dev/async/future/. Is this normal? If I've made any mistakes, please let me know. Thanks!

Version: signals_flutter 6.02

API description:

.refresh()
Refresh the future value by setting isLoading to true, but maintain the current state (AsyncData, AsyncLoading, AsyncError).

final s = futureSignal(() => Future(() => 1));
s.refresh();
print(s.value.isLoading); // true

.reload()
Reload the future value by setting the state to AsyncLoading and pass in the value or error as data.

final s = futureSignal(() => Future(() => 1));
s.reload();
print(s.value is AsyncLoading); // true
