The article quotes Chris Sheldrick,the co-founder of What3Words:
"...... anyone conducting a "systemic search using of our software" would come across examples, but they represented a "one in 2.5 million" occurrence, ......"

Again, starting with my front door location, I dropped the "s" from the other word and found a location in Wallingford, Connecticut. From there, I changed the first word from present tense to the past tense ("..s" -> "..ed") and got a location in Stamford, Connecticut - about 50 miles away. That seems close enough for confusion.

My search wasn't very systematic - just a stab in the dark using a likely variation which came up with the result first time. With odds like that, perhaps I should buy a lottery ticket.
