jQuery connected sortables behavior with tolerance set

jQuery connected sortables behavior with tolerance set

I have a sortable list with tolerance set to "fit". This allows me to drag items around the screen and release them on other droppables and when released it reverts back to its list in the position it was pulled from.  With one exception when i add 2 lists to the page and connect them moving an item from #listone over and then up still moves it into #listtwo.   So 2 connected sortable lists with tolerance set to "fit" allow items to be moved between lists far to the left or the right of the lists regardless of the current "tolerance" setting.

what I'm trying to achieve is essentially tolerance "fit" functionality for moving items between two connected lists.   I dont want an item I'm moving in #listone ending up in #listtwo unless  I release it directly over #listtwo

anyone have any suggestions?
