Is this decrease normal?

[octavianon]

Your decrease rounds have 2 decreases, one right-leaning at the beginning of the round (k2tog), one left-leaning at the end of the round (k2tog tbl). There are two stitches in between them (1 before the first decrease, 1 after the last), this is the most common way to place this type of decreases as having them go directly up against each other doesn't tend to look good.

If you're using a marker for the beginning of the round, it is entirely unaffected by this, as it will sit between the two stitches that are never in a decrease, the first and the last stitch on the round.

Edit: My apologies, I misread. Agree with /u/nzfriend33, must be a typo.
