twist ribbing Berroco pattern

[dicon77]

Good morning to all.

Sweater pattern: http://www.berroco.com/exclusives/dan/dan.html

STITCH GLOSSARY
LT2
Skip the next st, k the following st TBL, k the skipped st
RT2
Skip the next st, p the following st leaving st on LH needle, p skipped st, slip both sts off LH needle together

INSTRUCTIONS: Twisted Rib:
Row 1 (RS): P1, * LT2, p1, rep from * across.
Row 2: K1, * RT2, k1, rep from * across. Rep these 2 rows until piece measures 3”

MY QUESTION:
When doing this ribbing, should I be using a total of 5 sts when they say *LT2, p1* -- meaning should I twist two sts, then twist two again, then purl one.

I did not do this, I twisted two sts, purled one instead of twist 2, twist 2, purl 1, and it pretty much looks like mish-mosh, not a ribbing as shown in the photo.

I noticed that later in the pattern, it says to work over 7 sts:

Establish Pat St:
Row 1 (RS): K2(4-6-7-9), work Row 1 of Twisted Rib over 7 sts, * k7(8-9-10-11), work Row 1 of Twisted Rib over 7 sts, rep from * 4 times more, k2(4-6-7-9).

ANOTHER QUESTION: Regarding the twisted stitch itself, I see different ways to do it. Berroco instructions tell you one way (noted above), and when I search their videos, they do show an easier way, so do you think I could do it the easier way, assuming the video is newer than the pattern?

thank you all for your help with this and past questions. Jodi
