Exactly, Ive been on about 4 boat dives and NONE of them did any of this. They all just said something along the lines of, 'we will all just stay together, keep the DM notified of your air and everyone should surface with 500 in the tank, alright, lets go diving!'.
This sort of thing seems contrary to my dive training and in each instance I just made a plan with my buddy and dove that plan while staying with the group. Especially when visibility is like 20ft or so there is no way 10 people can be in a group and be able to see each diver at all times (youd have to be stacked like sardines), yet every guided dive Ive dove with has used that same dive plan regaurdless of low visibility.
Don't be bashful about asking for clarification. It's not a sign of inexperience to ask. If you don't understand a certain thing, there are probably others on the boat that also don't understand, but are too bashful to ask. OTOH, it may also have been covered by a general boat briefing done even before boarding, or the DM may just assume that you all remember certain things from diving with them the day before. In any case ASK FOR CLARIFICATION!
With a diveop/DM I haven't dove with before, I often get strange looks when I ask "How many divers will be in the water?" Kind of like the inverse of your

Basically what I mean is I dont want anyone depending on me as a group member when I am diving with my buddy,
, I usually know where all members of the group are at any time. When starting out in diving, it's hard to keep track of myself, much less a buddy. Then it starts getting easier. Then as you pay more attention, you find it easy to keep track of 6 or 7 divers while enjoying the dive yourself. You also learn that by watching those other divers, you will get to see more interesting marine life --- 6 pairs of eyes spot more than just 1.
Lack of prior agreement on ascent procedures has caused many incidents. At least once on Scubaboard someone reported an incident where they incorrectly assumed that the DM was their buddy and would ascend with them when they hit the ascent pressure. This led to a situation where the diver delayed his ascent to the point of being low-on-air.
Lack of prior agreement on lost contact procedures has caused excess excitement on the part of DMs and boat crew when either solo divers or a buddy group just "went missing" and continued their dive for many minutes after losing contact. Particularly, if the missing diver or buddy group is not aware of currents and/or agreed upon pickup point, this can easily lead to problems.
From your last post, it sounds like it was a live boat drift dive. The reason the crew/DM can get away with such a minimal briefing is that they don't have to worry about getting airhogs back to the anchor or mooring line. The boat drifts along watching the bubbles and picks up any divers that ascend early, as long as they stay more or less above the group.
