Interesting! You are right....
Even more interesting, 
If we read the UPA rules, we find this is spelt out some more:
----- Notice part (3) ----

2. Continuation Rule: 
    A. Disc In the Air 
        (1) If a foul, violation, or pick is called while the disc is in the
        air, the play is always completed. 

        (2) If the team which called the foul, violation, or pick gains
        possession as a result of that pass (e.g., an incomplete pass
        following a traveling violation, or offensive foul), play
        continues unhalted. In this situation, players should call
        "play on."

        (3) If the pass is completed, but the defensive effort on the
        pass was affected by the violation (e.g. picks), the pass does not
        count and possession reverts back to the thrower. 

It says "if the defensive effort was affected by the pick
then it goes back to thrower;" implying, I guess, that 
if it was unaffected, the disc does *not* go back.

So, Neil is right -- what I said is correct for UPA rules but
it is not mentioned in WFDF rules. 

Often, WFDF rules are modified 
to match UPA rules, so it may be that this part of the wfdf rules 
will change in the next edition. (The UPA rule above is a recent 
modification to the UPA rules.)

Anyway, that's the way it stands at the moment.

Does anyone still want to know where the up to date rules are?
I hunted around on the web and found the official WFDF and UPA 
rules. I copied them to wol also, so you can take your pick from the 
following links:
