I think what you're focusing too much on is the statement that the obstructed runner can not be put out between the two bases where they were obstructed. That is most certainly true. However, that doesn't mean that you necessarily only award just the one base.

Go back to my original statement about OBS. You award the base the runner would have reached had there been no OBS. The statement you make about the runner not being able to be put out between the two bases where they were OBS is one of the stipulations I had alluded to. That statement simply adds a layer of protection to the runner, nothing more. That same statement is not saying that the runner MUST be out if they advance beyond the two bases they were between. It falls right back to: award what they would have reached.

Take this sitch...

B1 is a fast runner, and she hits a good shot to the gap in the outfield. Easy triple for her. However, the catcher parallels the 1B foul line, but trips halfway down, falling into the path of B1. B1 trips over F2, stumbles, touches 1B, and goes for 2B. She gets tagged out.

Are you saying that you would only award 1B to the runner, even though you knew right away that she could have easily made it to 3B?
