Toe up sock increases?

So, I’m knitting my first pair of socks for my husbands Oma for Christmas. I’m about an intermediate knitter, but the phrasing on this pattern has me stumped. I’m sure i’m just over thinking it.

Its supposed to be dpns, but I prefer magic loop, but i know every six stiches is where the new needle would be.

Increases are every other round, so i’m assuming just knit in between. Then the pattern has it like this:
N1 and 2: K1, M1, knit to 1 st. before end of needle 2 m1, k1 So that would be the front half of the sock?
N2 and 3: K1, M1, knit to 1 st before end of needle 4, m1, kn1. And the back half? but wouldn’t this be needle 3 and 4 not 2 and 3?

Like I said, I’m sure i’m just overthinking it.

You have the right idea. It’s increases on either side of the front (instep side) and back (sole side) of the sock.
Since the pattern direction mentions needle 4 then you’re right, the N numbers at the beginning of the row should be N3 and N4.
And yes, it’s likely knit one round without increases in between the increase rows.
What a nice gift for Christmas.
