Help with chilly podsters

hi there, another question about the chilly podsters i am knitting. they are convertible gloves. i am at the part where you start the mitten top, i am very confused could someone please explain which side the opening for the mitten top should be facing?
here is the link for the pattern.

thanks, also i am avid knitting, and have knitted mittens before but this is my first time making convertible mittens.

The opening for the flip top should be on the palm side, the attachment is on the back of the hand.
