Some codecs (and by extension, some video players), tend to hitch when skipping backwards since they don’t necessarily store enough keyframes.

So if you have a choice between “skip back three times and get the weird half-decoded video or hitching three times” vs “skip back too much and then skip forward/watch the video”, the latter can technically provide a better experience. Especially if you’re streaming the data and it may have discarded what you’ve watched already or you’ve skipped a chunk and it was never loaded.
