This has been pretty inconsequential in the past but now that you can

But - why on Earth would it happen?

Simply because Willy remains above the item [i.e. two rows or more above the platform below the item] for nine consecutive time-frames whilst he's at the apex of a jump. That's enough to horizontally clear two complete cell-columns (i.e. eight animation-frames), without his attribute coordinates coinciding with the item.
I think the wider question is why he can't also do this for head-height Fire cells. To which the answer is - he can be killed by a Fire cell underneath his sprite whilst he is cell-aligned. He can only remain at a height greater than two rows above the platform from which he attempted to jump over the Fire cell, for seven time-frames. So he either clips it on the way up, or on the way back down. Unlucky!
