It does sort of look that way, doesn't it? I think the code suggests the HoA structure though. If he were using code references, the assignment line would be more like  ($value1, $value2)= &{$ref->{$key}} with the assumption that the referenced function returned a list. If the referenced function returned a pointer to an array then the assignment would be  ($value1, $value2)= @{&{$ref->{$key}}} which is getting decidedly unlovely in appearance.
