Steering Pivot Position Variations

I really would like to solve this question:

"Does the steering pivot axis need to go right through the middle between both hip joints in order to avoid pedalling/steering interferences (PSI)?"

For clarification and brain storming have a look at the following examples of bicycles with moving BB:
