AttributesRaw Array in Item API Questions

I was going through all the Attributes Raw Arrays. I noticed, at least in any of the items I have loaded that every attribute has a Min / Max value, yet I have yet to find any min / max combo that weren't exactly the same.

Is this intended? Is there ever any scenarios that they are different Values?

I'm trying to decide if i really need to implement both values in my App..

examples:

"Durability_Cur" : {
"min" : 562.0,
"max" : 562.0
},
"Damage_Weapon_Bonus_Delta#Physical" : {
"min" : 252.0,
"max" : 252.0
},
"Attacks_Per_Second_Item" : {
"min" : 1.100000023841858,
"max" : 1.100000023841858
},
"Vitality_Item" : {
"min" : 102.0,
"max" : 102.0
},
"Damage_Weapon_Delta#Physical" : {
"min" : 161.0,
"max" : 161.0
},
"Damage_Weapon_Min#Physical" : {
"min" : 318.0,
"max" : 318.0
},
"Durability_Max" : {
"min" : 562.0,
"max" : 562.0
},
"Damage_Weapon_Percent_Bonus#Physical" : {
"min" : 0.28,
"max" : 0.28
},
"Intelligence_Item" : {
"min" : 267.0,
"max" : 267.0
},
"Damage_Weapon_Bonus_Min#Physical" : {
"min" : 123.0,
"max" : 123.0
}
},
