No, that was due to them both being re-incarnates and both possessing SP Chakra which was awakened thanks to borrowing Hagoromo himselves SP Charka.. they are linked and no, its not by Hagoromo's chakra, because they don't have his DNA implanted therefor they can't regenerate HIS chakra. Thats like saying Tsunade now gerenates Dan's chakra because he let her borrow his chakra.
