[jQuery] jquery form plugin ajaxSubmit / fieldvalue inconsistent behaviour [jquery form]

if you have in html the following:

<input type="checkbox" value="true" name="check"/>
<input type="hidden" value="false" name="check"/>

ajaxSubmit will submit :

check : true
check : false

$("#check").fieldValue() will return
[ true ]

so, this is inconsistent with the result of ajaxSubmit, it should
return  [true,false]
