Hibernate: @Embeddable groups columns without a table

@Embeddable
record Address(String line1, String city, String postcode) { }

@Entity
class Customer {
    @Id Long id;
    @Embedded Address home;

    @Embedded
    @AttributeOverride(name = "city", column = @Column(name = "billing_city"))
    Address billing;
}

One table: customers(id, line1, city, postcode, line1, billing_city, postcode)
AttributeOverride is required whenever the same embeddable appears twice.
