Proportional editing connected mode is using the graph distance (the distance calculated when traversing the mesh to find connected vertices) rather than the Euclidean distance. The behavior seems to have been altered on Feb 1, 2010, with commit 26537 "Proportional Edit Connected: Use connectivity distance for falloff (connectivity distance now also calculated across inner face edges)."
Reversing the behavior can be easily accomplished by deleting three lines of code (lines 1724-1726 in transform_generics.c). However, I don't know what effect this would have beyond fixing the behavior of mesh editing with proportional editing connected mode. Does someone know a reason for using the graph distance rather than the Euclidean distance?
