Noob Hops Grower Question

As the saying goes, there are no stupid questions but there are a lot of inquisitive idiots! As a hops growing noob, I feel as though I have to ask this.

Why are these things called bines and every other climbing plant is a vine?

By the way, here is what I got from dictionary.com:

American Heritage Dictionary - Cite This Source - Share This bine (bīn) Pronunciation Key

As "I" understand it has to do with the physical make up of the main trunk and how it attaches itself.

Vines, IIRC, typically have a sucker type stryucture that attaches to it's "host" support.

Bines, again IIRC, use tiny hair like spurs to hook onto the structure (which is why a textured support is necessary).

I could be waaaay of here.

Another thing too is that hops grow in a clockwise pattern looking down at them. This causes them to wrap around poles and other things that can support their weight.
