After a second look on that issue it seems that the code works properly
even in that case - en->lb, which is returned by calc_next_hop(),
is updated in link_back() before each call to calc_next_hop().
Therefore, for each connection it returns proper next hop address and
these are later composed to the multipath nexthop.
