The question can be rephrased like this: the curve is not exactly on the location as expected in the original data. Some of segments may be affected by surrounding data values, for example, the curve may be "attracted" by regions with high data values.

This is because of the algorithm we use for the curve drawing. This algorithm is described in the paper:
Peng, H., Ruan, Z., Long, F., Simpson, J.H., and Myers, E.W. (2010) “V3D enables real-time 3D visualization and quantitative analysis of large-scale biological image data sets,” Nature Biotechnology, Vol. 28, No. 4, pp. 348-353, DOI: 10.1038/nbt.1612. ( http://penglab.janelia.org/papersall/doc... )

So based on this algorithm, if there is a difference between the drawn curve and the expected curve in the original data, the reason is mostly because of the viewing direction that the user uses for drawing the curve. Changing to another viewing direction may increase the accuracy of curve locations.
