(Which is one reason Pluto was expelled, it has a different orbit).Your orbital axises would have to be different meaning the moons would cross paths  (in relation to each other) at least twice causing an Umbral Eclipse twice during the rotational cycle.  Otherwise your planet must have two gravitational centers.  For evidence of this, look at the multiple paths of Saturn's and Jupiter's moons, they have "atom-like(orbital model)" paths around their respective planets which from the surface would cause the moons to "disappear" for a time as they duck behind their stellar cousins.  Of course if the moons have different sizes in terrestial viewing (ie one is visually larger from the planet's surface) the point is kind of moot, though the resulting Lunar eclipses could be really interesting and possibly cause for some sort of "superstitious" mumbo-jumbo that will give your cosmos some credence.  Also the solar eclipses should be stunning.  <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f600.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":D" title="Big grin    :D"  data-smilie="8"data-shortname=":D" /></blockquote>
