Beginner Gardening: Pink Jasmine: where does new growth originate?, 1 by Twincol

I'm curious.

I'm unable to determine the "origins" of new season's growth following the Spring Flower. The vine is, as many of you no doubt know, packed with green stems of the passed flowers. I would like to truly "train" my vine so as to have a bit more control over it's path across the metal fabric fence. But I simply cannot find out what happens with these "bundles" of stems. I mean . . . this vine is so "woundaround" that it is impossible for me to figure out earlier patterns.

The photo here shows the entire tip of a branch with numerous flower stems. The next photo is the same branch closer up. The displays the earlier branchlet (?) a tad long and without apparent flower stems (top right), with several pair of flower stems and new growth tucked in with each pair. When I look at similar branchlets the distance between each pairlet(s) is considerably longer . . . which causes me to consider that the branchlet between them grows as the new branchlet develops. How's that for a convoluted sentence? My botany ignorance is certainly evident here, eh?

Would someone please reduce that ignorance for me? And if training this massive cloud of wondrous vine is neigh impossible, at least my curiosity will be satisfied.

Oh, and would simply pruning this back to the fabric fence along the length of the fence, fill in the lower fence? Or is growth always at the upper fence despite any pruning?

TIA to my wondrous gardening friends,
