The latter is probably very close.
69 Topps had a fairly complex layout, with different a and B sheets, and some doubleprints. (actually double prints and triple prints, a fine distinction)
So some cards have 3 positions, and most have 2.
Each color should be taken on its own, so the WN/YN is a change in the Yellow, but the Blue mark is a change to Cyan*.
So one of the positions could have had a fault in the Cyan layer, that they didn't fix. When they fixed the Yellow layer the new set of plates would have the fixed yellow, but still have one position with the unrepaired Cyan.
At the craziest not likely, but possible - A first set of plates gets made with a good cyan layer but a bad yellow layer. The cyan mask gets damaged, and later the yellow layer is fixed and new plates are made. Still later the blue is fixed, and the yellow is still fixed, resulting in three versions, two of which are very hard to tell apart. (Or mix in a hand done fix for the blue mark, which would be a pretty rare thing)
Think that can't happen? I just went through the 49 leaf set, and found three -four major changes, plus transitional cards. And that's just in a month or so of looking seriously for the different varieties on Ebay.
*It can also be a change in any or all the other colors, I'd have to see a high res scan or have one in hand to be sure. That would indicate a problem on the pasteup that got fixed.
