There is a sequence flow from that task to the Approve Travel Request approve human task in the bottom swimlane.

There is a sequence flow from the Approve Travel Request task pointing to the Approved? gateway in the bottom lane.

There is a No sequence flow pointing from the Approved? gateway back to the Redo Travel Request task in the top swimlane.
