Ok, let me break it down.
Comics have a visual language. Comic panel counts are part of that visual language. They control time, space, urgency, emotion, and pacing. Even if you are not doing traditional style 'pages' (and most webcomics are), you are still working within a two dimensional space that is still subject to the same restrictions in story telling as the normal page.
In a comic, each panel is supposed to advance the story. Each panel is not a moment of time, but rather a variable amount of time determined by the panels content. You can show a tenth of a second in a panel, or you can show hours. The point is, there is a visual language and an expectation of the reader.
If you have a highly decompressed story with lots of splash pages, you are changing that language in a way that has a large chance of not conveying your story to your audience. You see this with a lot of the disconnect between the American, European, and Manga fans. Part of their problem is that each of those styles has a different visual language that goes far beyond art style.
So no, this has nothing to do with 22 pages a month. It has to do with the extreme decompressed style (and I prefer decompressed over compressed, but the extreme version takes it to far) drawing things out until the story is negatively affected by the lack of advancement and the over-dependence on the art to try to save a weak story.
When writing, the first thing that one learns is that if it does not advance the story, take it out. In story telling for comics, the same thing applies. If that panel does not advance the story, lose it.
When writing, you learn that you have to watch the emotional highs and lows of your writing, that you have to pace them so that you do not cause your reader to lose interest as a result of emotional exhaustion. Things such as huge panels and splash pages should be reserved for emotional highs for the same reason.
Writers are cautioned to not draw out a story beyond what it needs to be. Don't try to stretch a short story into a novel. Comics are the same way. Tell the story, don't draw it out, or the only thing you have left are pretty pictures.
