Russian user here. Yes, that's weird. I would expect something like Maxim Igorevich Popov.

There are no patronymics in Russian passports at least, not sure about Ukrainian. But even if they are, it would be Igorevich 100%. And it's always written on American visas as in national passport.

Vladimirovich is not a second name, it's patronymic (name of his father)

What a bs. Russians/Ukrainians do not have second names.
