double first base

[Gmoore]

Fed rules................

Runner on first, she is standing on the orange part of the safety base while getting sign from 3rd base coach, pitcher has ball in circle, Base umpire call runner out for being off "base" while pitcher has ball in circle.

your call???

I can’t find any casebook plays anywhere near this play, I have a no call here, but I few people seems to think the orange base disappears after initial play others say it becomes one big base looking for help with rule and or interpretation
