PBUC and an overthrow/obstruction

[devilsadvocate]

From the PBUC Manual:
"if a throw is in flight at the moment the obstruction occurs (umpire calls "Time") and if the throw turns out to be wild and goes out of play, all runners will be awarded two bases. In such cases as this, the umpires have the responsibility of determining whether a throw is made before or after the obstruction, If the umpire judges that a throw was made after the obstruction, the obstructed runner will be awarded only one base from the base he last touched at the time of obstruction." The underlining was my emphasis. I guess the bold, blue, and green are my emphasis too (grin).

OK, this has me confused. So enlighten me. This section deals with Type A obstruction.

In the blue part, all runners are given two bases. This is the normal award for a thrown ball that goes out of play. So are we basically ignoring the obstruction and awarding the bases based on the overthrow?

In the green part, the obstructed runner only gets one base if the ball goes out of play, and I assume the other runners get two bases on the overthrow. That seems to be penalizing the obstructed runner. Or does it mean that he would get one base on the obstruction, then two bases on the overthrow?

Any help on this would be appreciated.
