A slight change of ordering makes your point. Team A drops back to pass and holds a Team B player going towards Team A QB. The QB then throws an interception. In that scenario, Team B would decline the holding penalty, upholding the interception.

Regardless, your second example, of the offense committing holding and the defense declining due to an interception is legit. That happens occasionally.
Edit: I think we just took what was more important for the OPs point differently. I took the point as a penalty occurred, not a specific one. And you see it as "how could holding have happened". Which, if we are being pedantic, also wouldn't happen in the scenario you described. If it was called holding, it would have had to occur before the pass, making it not OPI. =).
