It looks to me as if 1) they are the same man and 2) there are two marriages.
Etienne POUSSIER, of Lonrai, Orne, France, married Jeanne LECONTE of Damigny, Orne, France on 10/11/1547 at Alençon, Orne, France
Etienne POUSSIER, of Lonrai (Lonray [sic]), Orne, France, married Jeanne BOUGIS on 02/05/1559 at Alençon, Orne, France
My take on it anyway.
