Let's assume your video and audio are not perfectly in sync, cause of minimal differences in video clock, cause of latencies in the video material itself - we think of only 3 seconds are wrong within 90 minutes.
3 seconds are 3000 ms - so audio and video will slowly diverge over time.
In passthrough case, we only can drop or dupe, which means we can add an additional 32 ms package or we remove one 32 ms package - that will do "ckrrrrrch" or "click". That will happen perhaps 10 times during that playback time, let's assume 5 times add (you don't hear) and five times drop. So 5 clicks during the movie.
Now with resample, there are ten occasions of 32 ms time, where audio is "shortly resampled" - you won't even realize that :-) I am sure.
