How do I handle multiple instances of segments that cover the exact timestamps?

For example,

{
“video_uid”: “736fd0be-9335-48d8-aa67-680b0c683efc”,
“clip_uid”: “d84b8c76-d6b9-4e27-ae66-b010bce5ed1e”,
“clip_parent_start_sec”: 0.0,
“clip_parent_end_sec”: 308.0,
“clip_parent_start_frame”: 0,
“clip_parent_end_frame”: 9239,
“interval_start_frame”: 0,
“interval_end_frame”: 8999,
“interval_start_sec”: 0.0,
“interval_end_sec”: 300.0,
“verb”: “put_(place,_leave,drop)",
“noun”: “iron”,
“action_clip_start_sec”: 268.9543619333333,
“action_clip_end_sec”: 276.9543619333333,
“action_clip_start_frame”: 8068,
“action_clip_end_frame”: 8308,
“action_idx”: 94,
“verb_label”: 65,
“noun_label”: 216
},
{
“video_uid”: “736fd0be-9335-48d8-aa67-680b0c683efc”,

“clip_parent_start_frame”: 0,
“clip_parent_end_frame”: 9239,
“interval_start_frame”: 0,
“interval_end_frame”: 8999,
“interval_start_sec”: 0.0,
“interval_end_sec”: 300.0,
“verb”: "take(pick,_grab,get)",
“noun”: "cloth(cloth,_fabric,_garment,_kanga,_rag)”,
