Ok....so how does the offense know whether #1 or #2 is in effect? I don't see them looking to the sidelines until it seems to be decided that #2 is what is happening. What is the signal that causes them to get out of the set formation and all look simultaneously to the sideline?...
When you are in this mode, it's automatic, you are expecting to get an audible during the "ritual" cadence from the QB to stand up and check with the sidelines. It's by design.
No, they are not looking at the sidelines to get a [U]different[/U] play all the time because #1 (same play) might be still in effect (OKed, greenlight) and the team is signaled to run it. You go through the same exact "check with me" motions whether #1 (same play) or #2 (different play) is in effect.
NOTE: there are many kind of uptempo systems and at least 3 kinds of speed. I'm describing the most typical mode. At "warp speed" (or whatever the proprietary term used in the system, ie. "turbo"), you're not looking at the sidelines at all. The QB gets the signal and runs around relaying it as fast as possible. In some modes, only the Specialists (the QB, WRs, TEs, and RBs) look at the sideline.

....And I've always had another question about this....why couldn't defensive linemen interpret this standing up business as illegal procedure movement and hit someone for an offensive penalty?
No, it's not illegal procedure because the OLM aren't going to 3-point stances, which would make them permanently "set". They aren't not set if they stay hands-on-hips (2-point stance) as you see happening....but the D has to be ready because the O can still run a play at this juncture.
