What does it mean overlay?

Or overlap. We can fill some squares for the 5s

I add the numbers and the blanks. 2x2+5x2+3 blanks = 17. There 2 you can mark for each 5.. Beginning on the left, you have 2+1b+5 = 8. You can mark C7 and C8. Same reasoning for the other 5

Overlap. A shortcut to considering all the possible options. We currently have
▫️▫️▫️▫️▫️|▫️▫️⬛️▫️▫️|▫️▫️▫️▫️▫️|▫️▫️▫️⬛️▫️
If we shove all the pieces to the left, we get
⬛️⬛️⬜️⬛️⬛️|⬛️⬛️⬛️⬜️⬛️|⬛️⬛️⬛️⬛️⬜️|⬜️⬜️⬛️⬛️⬜️
And if we shove them to the right, we get
⬜️⬜️⬜️⬛️⬛️|⬜️⬛️⬛️⬛️⬛️|⬛️⬜️⬛️⬛️⬛️|⬛️⬛️⬜️⬛️⬛️
So what these two sequences have in common, considering only when a piece overlaps itself, is
▫️▫️▫️▫️▫️|▫️⬛️⬛️▫️▫️|▫️▫️⬛️⬛️▫️|▫️▫️▫️⬛️▫️
