Poorly worded; and a path needed two points not clear enough.

ok.

i am looking for a visual representation of this key agreement
sequence; it's a weird beast like constructed modes of operation.

there are good elliptic curve demonstrations, but none covering
supersinguler EC DH

thanks for patience, may others be more helpful!
