ECP::muln() bug?

[blynn]

I may be using the API wrongly, but I think the 3 print statements in the following program should agree:

extern crate core;
use core::bls12381::ecp::ECP;
use core::bls12381::big::BIG;
use std::vec::Vec;

fn main() {
    let g1 = ECP::generator();
    let x = BIG::new_int(1);

    let mut ps = Vec::new();
    ps.push(g1.clone());

    let mut xs = Vec::new();
    xs.push(x.clone());

    println!("g1: {}", g1.tostring());
    println!("mul: {}", g1.mul(&x).tostring());
    println!("muln: {}", ECP::muln(1, &ps, &xs).tostring());
}

However, I got:

g1: (17F1D3A73197D7942695638C4FA9AC0FC3688C4F9774B905A14E3A3F171BAC586C55E83FF97A1AEFFB3AF00ADB22C6BB,08B3F481E3AAA0F1A09E30ED741D8AE4FCF5E095D5D00AF600DB18CB2C04B3EDD03CC744A2888AE40CAA232946C5E7E1)
