H2D Extruder Order - Right Prints First

What drives the printer to start with the right extruder, then the left extruder color on the first layer? Is there a way to tell it to use the left extruder first, then the right? The numbering for my colors (2 color print only) is left 1, right 2, but the print starts with extruder 2 first. Guess its not a problem what order it goes in, just curious how it decides. I would expect it to start with the left number 1 color then go to the ams/right extruder for color number 2.

Thanks
