Hmm I always thought lorem ipsum was a text with letter usage histograms similar to English, without distracting the reader with meaning. I could have sworn I read that somewhere...
It does likely have relatively similar usage patterns to English in terms of letter distribution, if only because they're both indo-european languages and English has deep vocabulary ties to Latin through Norman influences.
“Pencil what comma building twenty section human fedora”
is English, even if it makes no sense.
No, "Lorem" is "dolorem" with the first part chopped off, "adipiscing" and "elit" are mangled non-words, too, and so on.
"Pencil what correct horse battery staple" can be called a sequence of English words. If someone who doesn't know what they're doing writes "ncil what correctando taple", though, then you're no longer in a position to say, "Those are English words".
