Generalization of Features and Search Widget

Does anyone understand the line below in the _onSelectResult method in the Widget.js file of the Search widget in Web AppBuilder? I am trying to learn about graphics and generalization. The first thing I wanted to understand is why the highlights in the Search widget are greatly simplified. I have a 61 vertex pipeline that was simplified to 6 vertices and it is very jagged. So, I am going through the code and trying to understand it. As part of that process, I ran across this code as a possible clue. I want to know why selectedFeature is simplified and resultFeature is not. resultFeature appears to come from the on select result event. selectedFeature comes from layer.queryFeatures. I even tried to set maxAllowableOffset on featureQuery and I still got a simplified feature for selectedFeature.

layer.queryFeatures(featureQuery, lang.hitch(this, function(featureSet) { var selectedFeature = null; if(featureSet && featureSet.features.length > 0) { selectedFeature = featureSet.features[0]; // working around for js-api's generalization. // incorrect geometry of polygon result of queryFeatures. selectedFeature.geometry = resultFeature.geometry; this._loadInfoTemplateAndShowPopup(layerInfo, selectedFeature, e); } }), lang.hitch(this, function() { // show popupInfo of searchResult. var selectedFeature = resultFeature; this._loadInfoTemplateAndShowPopup(layerInfo, selectedFeature, e); }));

Any help would be appreciated towards understanding the Esri developer's comment on generalization or why the Search widget highlights are generalized.
