I do not want to get too detailed because I am not sure what the exact question is honestly. But a lineman, once they put their hand on the ground in a stance, lifting up that hand, would be a false start, not an illegal shift.

Interior lineman is usually a player in a position where they are on the line and has someone on both sides of them. A lineman can be a person that is in any stance, but not eligible by position, not just by number.
