Contour with Barriers vs. Contour

I've noticed that working on the same DEM, the shapefile output for 'Contour' and 'Contour with Barriers' is quite in the amount of contours created.  On the DEMs I'm working with, 'Contour with Barriers' seems to never create contour segments that are less than 27 meters in length while 'Contour' will create contour segments that are extremely small in length (hundredths or thousandths of a meter, maybe more...I can't recall).

Can anyone explain why this works this way, including the determination of minimum segment length.

Thanks in advance,
Wes
