As Chris mentioned the rendering engine looks at the geometry bounds
to determine whether the feature is drawn or not:

    drawFeature: function(feature, style) {
         if(style == null) {
             style = feature.style;
         }
         if (feature.geometry) {
             var bounds = feature.geometry.getBounds();
             if(bounds) {
                 if (!bounds.intersectsBounds(this.extent)) {
                     style = {display: "none"};
                 }
                 return this.drawGeometry(feature.geometry, style, feature.id);
             }
         }
     },

So if the bounds received from the server aren't incorrect OpenLayers
may not draw the feature while the feature is in the current extent. I
tend to think that determining whether the feature should be drawn or
not is an internal thing that should be based on an internal
calculation.
