Knitting sock question

I am knitting my very first sock and I got to the heel flap last night. Now, the instructions said "slip last 12 stitches onto needle, then knit first 12 stitches onto needle…and I think I did it wrong. Crap crap crap.

Never mind.

I am doing the magic loop method, so I divided up my stitches, and then slipped the first twelve off and then knitted the next 12, and then put the next 24 on the resting needle for the instep. instead of knitting the 12 on the other side of the needle. But it looks right.

Anyone familiar with knittng one sock on ML?
