Unless the question has been edited recently, it did. There are multiple lines in the second example input that show the overlap:
> eightwothree
> 4nineeightseven2
> zoneight234
I test my AoC solutions incrementally by printing output, so I found that I was failing to produce the correct list of numbers in a line right away. I suppose if you're taking a faster approach and just trying to extract the first and last numbers that it's easier to miss. It's always a good idea to look at the example input, though.
