The logic is assuming that once we reach the end, the floodgates will open and shops will have issues 93-98 on store shelves at the same time. (Which most shops don't ahve space to front-face all that.) If there was a delay on everything, then you'd just get 93 as the next issue, but if digital is up to 98, you can't just release 93 alone, since you're playing catch up. Hence why most were calling for an outright delay.
So, assuming a reader has a finite week-to-week budget, they have to pick and choose. Whereas they would've bought say Batman, Batgirl, Lois Lane, and Strange Adventures in one week, now they have to decide if they're buying 4 issues of Batman or whatever. Basically, if you're on a weekly floppy budget, the floodgate model is bad for you. Or, as others have mentioned, you just stop reading comic altogether.
You've introduced an interesting cluster to making whatever sales you might get on digital. Either way, it either shift the market towards digital, or causes other unforeseen issues. And if digital doesn't match the sales you're looking for, the Big Two are going to cut teams regardless, because they won't be profitable.
This assumes we're looking at a gap of 2 months or longer, but you get the idea.
