None About Volumes and Tracks

I am still fairly new to the Geant toolkit. I hope someone can answer this question for me.

Say I have a world volume of water, and I put blocks, also made of water, inside it. I run a simulation and get certain trajectories. Now if I remove these water blocks, nothing has been changed in terms of the composition of my geometry, but the resulting tracks would be significantly altered.

For example, if I fill the world volume with say, 50x50x50 blocks of water (for dose scoring), there will be many steps in each track, due to crossing of boundaries. The electron tracks would travel in a more zig-zag pattern compared to the tracks with the world volume alone.

Why should this be when the composition of the geomtry in both cases is the same?

Thank you in advance, Michael
