Construct Polygons (with Use existing features in target) changes existing features

We use the Construct Polygons tool with the Use existing features in target option (ArcGIS 10.1 SP1, Sql Server 2008 SP2 versioned GDB) to construct parcel polygons using selected line features from another feature class which exists in the same geodatabase/feature dataset. We have no database topologies set, and do not use map topologies. I find that the tool sometimes (most times?) will slightly change the geometry of the existing features used to construct the new polygons. Afterwards, when using the Version Changes tool on the edit version, these adjacent (existing) polygon feature(s) will be listed, but will sometimes have no values (including Shape/SHAPE.Area/SHAPE.Len) displayed in bold to signify any change to the feature. Does this tool, when used with this option, set up a map topology which may effect (change) the existing features? The documentation does not explictly mention topology. Is there any way to keep the existing features from being changed in this scenario?
