The rightly-named Orthodox Churches do not hold that one can be in two marriages at the same time.

Then there are only two other possible explanations for their practice of allowing second marriages while the first spouse is still alive:

1. They believe that under certain circumstances it's permissible to commit adultery; or
2. They believe that somehow the first marriage ended before one of the spouses died.

Neither of these beliefs is "orthodox" (with a lower case "o").
