Feedback CHOP modes

Does anyone know why the feedback2 with ‘Previous Channels at Current Time’ into a Delay CHOP seems to pass the signal fine in this example, but not the feedback1 with ‘Previous Channels at Previous Time’?

a TimeSlice CHOP instead of a Delay CHOP would display the same flat line.
The wave never steps into the present, so it leaves no memories.
inexistent from a time slice perspective.

an Extend CHOP set to cycle would make it visible, but same as feedback2.
