How to make an invisible bind off with double knitting

In this DROPS video we show how to make an invisible bind off when using double knitting.

To match the invisible cast on you will have to make a kitchener stitching at the end of your work. Separate the stitches in the front and back onto two separate needles.
Cut yarn and make one tail long enough for stitching, i.e about 3 times the width of your work. Put the long strand on the darning needle and the other strand will be weaved in later.

We have a separate Drops Video for Kitchener Stitch, but this is how you do it:

Stick darning needle purl wise into 1st st on 1st needle and pull through without dropping st off needle.
Stick darning needle knit wise into 1st st on 2nd needle and pull through without dropping st off needle.
* Stick darning needle knit wise into 1st st on 1st needle and drop off needle, stick darning needle purl wise into 2nd st on 1st needle and pull through without dropping st off needle.
Stick darning needle purl wise into 1st st on 2nd needle and drop off needle, stick darning needle knit wise into 2nd st on 2nd needle and pull through without dropping st off needle*.
Repeat *-* across

This video has NO SOUND - you must read the pattern to be able to follow this video properly.

After the yarn separated green and red, how about the green yarn?
Hv to cut it or just tied the green yarn.
Thank you😊
