Surface divide / split list issue

Hello, I'm new to Grasshopper and I'm learning with different tutorials. Now I have an issue with a surface divide. The component that I took from my grasshopper results a list of values. The surface divide of the tutorial results a list of coordinates. I'm trying to re-build a definition and my goal is to continue working with the selection of points on the left cylinder. Can someone please help?

Top definition is what I built. Lower definition is merged from the tutorial file...

The tutorial is using an obsolete version of the SDivide component. The new version's outputs are of "columns" of points instead of all the points for a surface. (This helps when trying to figure out points on trimmed surfaces)

The easy fix is to use a the Flatten function on the Split List input or alternatively the Flatten Component.

This way will limit you to having only one input surface for your definition. If you wish to have more than the Path Mapper with {A;B;C} --> {A;B} would be a better option.
