First off, sorry I confused you even more because I used a wrong word in one sentence, edited it now.
Two distinct styles are continental knitting (yarn coming from the left) and English knitting (yarn coming from the right). Both have slight variations with their own names but it kinda makes sense. The schematics you provided don’t demonstrate how the yarn is held or hooked behind the needle so it’s not specifically continental. However, the way the needle is inserted to the stitch and the direction the yarn is wrapped, that’s western mount. Good thing is, most infomaterials in English are based on western mount so the long descriptions of complicated stitches and decreases and all are based on it regardless of your continental vs English style so all that makes sense.
If you want some good visual for continental knitting, check out Nimble Needles or Roxanne Richardson in YouTube, both very proficient teachers. For Norwegian knitting check out Arne and Carlos, that’s a subgroup of continental.
If you want me to ramble about mounts or find good visuals, lmk, otherwise I feel like I’m dumping too much stuff on people who haven’t asked for any of it.
It’s a very good visual how the stitches are formed. The e-book you linked goes even deeper, showing all kinds of useful basic stitches and providing a few easy to follow patterns.
But I would argue those stitches in OP are not continental per se. Continental knitting refers to holding the yarn in left hand, opposed to English knitting where the yarn is held in right hand. The imagery is for knit stitches, western mount, meaning that the leading leg of the stitch is on the right. In western style the same, leading leg on the right, would apply to purl stitches as well, as seen in the book.
Edit: changed a wrong term. Somehow the thought was running too fast and the eye didn’t pick it up
