Suspension of the $(-1)$-sphere

My uncertainty is that I assume that the "part" of the vacant set that result of the item of among the endpoints of the line with the void is fallen down with a factor and also we continue this way with the various other continuing to be factor, yet the void no have factors, after that, where the factors originate from? Am I remedy with the thinking about collapse the void with a factor "two times"?
