Congratulations, you just found a fixed point attractor.

I think a fixed point attractor would be a word or phrase where it goes naturally but then doesn't have any more suggestions: a dead end.

This is more of a periodic-solution attractor.

"Facebook helps you connect and share with the people in your life and your business could subject you to lawsuits and leave your operating systems without patches"

Typing in "Larry and Sergey" produces

Larry and Sergey Dump Shares of the Company and their respective mascots, events and info in the top right corner of the world's largest international multimedia news agency

but after a few more phrases the story gets into a loop.

"It was a dark and stormy night in the city of New York City Area Directory of All Stores International Sites & Affiliates Forum & Resources for Teachers and Students at the University of California at Berkeley and the University of California at Berkeley and the University of California at..."

The cadence reminds me of a certain character from BSG. You tell me:

I guess this particular phrase has been on the internet so much that it skews the machine learning algorithm.

I have another question for yourself at their website and buy this product again and again and I'ma let you finish but Beyonce had one of these days I'll bet your life on the road today and

Indeed. The first sentence it generated for me was not a Markovian nonsense phrase, but rather a phrase that appears on a very large number of web pages: "The following content has been identified by the YouTube community as being potentially offensive or inappropriate." This gives some insight into their seed data.

Their seed data is probably the n-gram dataset that they released (or maybe a more recent one):

Microsoft also has an n-gram dataset that you can access through a web service:

"to their libraries and their users are not likely to become an editor... and really good food and good service is our number one priority is to provide and... they are nothing but another form of therapy for these patients is not known whether these are the only ones."

To prevent loops you can vary the selection, not just picking the top item, but perhaps doing something like 1-2-3-2-1-2-3

This actually produces less intelligible sentences, but more randomness

"dogs and azithromycin zithromax one dose chlamydia and gonorrhea are the most common form of dementia"

Just few spacebar and enter wrote this sentence: "What the hel* is this guy on their team and their fans are the best in the world of their owners and are strictly for viewing and printing of these books."
