Question about Dropping-In and Other Right of Way Rules

So I know that Waikiki is pretty much no-mans surfing land, but I am still curious as to how the official rules would apply and who technically has right of way. Correct me if I am wrong, but it seems the rule of not dropping in on others is mostly applicable in instances where you're surfing laterally across the wave, such as Pipeline, and thus cutting in front of someone essentially puts you in their surfing path creating a risk of collision.
However, in the south end of the island, the waves dont seem to really curl to any one direction with any level of speed when the surf is more mellow, thus everyone in the lineup more or less just ques up in the middle of where they think the wave will generate and then it's a drag race of 10 dudes trying to mount the wave. In that case, everyone is surfing straight, thus theoretically no one should be crossing paths, and so it's not really dropping in if you mount a wave with someone already on it as long as you do so far enough to the side of them that you wont hit them, and you dont cross your path with theirs. Is that correct?
My understanding of surfing in slower waves that dont have fast curls is more or less like this:
-If you're paddling to catch a wave and someone is already on it, you have to yield to the guy on the wave.
-If you're on the wave and someone in front of you is paddling to catch the wave, they have to yield to you.
-If multiple people are paddling to catch the same wave and they are all in close proximity, first to feet has priority. Everyone else can still catch the wave, but only if they do so in a manner that wont put themselves at risk of collision with someone who was first to feet before them.
Is my understanding correct?
