You don't have to reattach the yarn there, necessarily. If you're putting all your stitches back on the needle, you start knitting with a new strand if there's not one attached at the place you need to start knitting.
You can just start knitting with it and weave in the end later.

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
