List of arguments is empty when apply_filters is returned instead of assigned to variable

[LuigiPulcini]

There seems to be a difference in the output between the two following occurrences:

<?php
/**
 * My plugin filter assigned to a variable
 *
 * @param string $first_param This is the first argument
 * @param string $second_param This is the second argument
 */
$some_variable = apply_filters( 'my_plugin_filter', $first_param, $second_param );

return $some_variable;

<?php
/**
 * My plugin filter directly returned
 *
 * @param string $first_param This is the first argument
 * @param string $second_param This is the second argument
 */
return apply_filters( 'my_plugin_filter', $first_param, $second_param );

In the first case, the full list of arguments is correctly parsed. In the second case, the list of arguments is empty.
