You need two separate variables for the is-open attribute, working plunk here
Code changed:
$scope.status = { isopen1: false, isopen2: false }; <div class="btn-group" dropdown is-open="status.isopen1"> <div class="btn-group" dropdown is-open="status.isopen2">
It should be noted that the use of the is-open attribute is not required. You will notice that if you remove the is-open attribute with bindings, the dropdown menus will work.
