If they did not have a setup for recording during the first match, at least they know they'll be able to record it for the second match. Sounds like a less riskier option, as opposed to throwing the match and having the AI's TID/SID reset.

Also, bulbapedia has a page showing the 'glitch', with a linked video.
If I'm not mistaken, this Skarmory is the first battle too. (has Granbull, so it's not. Is Gonzap an avoidable trainer?)
Anyhow, those are just my thoughts.
I'm pretty sure this mechanic is well understood by now, but I felt that words from you would be more compelling.
