Well you obviously weren't careful enough. Nowhere in the article does he talk about a 4 GB binary or binaries. To quote him:"A 4GB Tex distribution dependant on over a 100 binaries" He is talking about the _whole_ distribution not a single or several binaries. So even though you were careful, you still misquoted the article.
"The App Store guidelines insist that any iPad app be a single executable. Jailbreaking would ease this restriction, but in this case Apple’s gatekeepers are right. A 4GB TeX distribution dependant on over 100 binaries is not acceptable on the iPad."
From that quote ("A 4GB TeX distribution dependant on over 100 binaries is not acceptable on the iPad."), it is clear that he is musing about a scenario where he ships all 4GB. As stated many times (and also in that same quote), on the iPhone you are forced to ship something as one executable. Thus, the theoretical distribution he is referring to would in fact be a single executable of about 4GB. In fact I think that's the whole point of those two sentences. So it appears that I was indeed quite careful.

On the other hand, yes the executable must be "one". On the other hand you can download stuff (either directly or via DLC). The issue is that while Apple has relaxed their restrictions on bundling interpreters in applications (you can do that), they have not relaxed their restrictions on downloading interpretable code: it's not allowed. So downloading even styles would be verboten, since styles are TeX, and TeX is executable code.
I think you are missing the point. The apple guidelines do not state that a program can only consist of an executable. That would not make any sense. Rather they state that any application can only consist of a single executable in addition to whatever resource files are included. In the case of the Latex distribution in question one would have to convert all 100 executables into one executable, my guess would be perhaps 100 megabytes. In addition one would have to include lots of resource files, mainly sty-files bringing the whole bundle of an executable + resource files up to 4GB.
AFAIK Apple doesn't restrict you from bundling files in your application. That simply wouldn't make any sense.
The point here is that he is talking about an application consisting of a single runnable binary of size X with tons of bundled .sty-files that brings the whole application up to 4GB.
Previously, this would not be allowed, since .sty-files are interpreted (which in turn would make it impossible to implement LaTeX on the iPhone), but that really wasn't the point here. The point is simply that this wouldn't be a single 4GB executable, but a an executable of perhaps 100MB bundled with a whole bunch of .sty (and other) files to a total size of 4 GB.
Edit: Fixed typos. Sorry. HN doesn't work very well on my phone.
