The average American watches more than five hours of TV per day, but pretty soon that leisure time may be dominated by YouTube and other online video services.
In an address at CES 2016, YouTube's chief business officer Robert Kyncl argued that digital video will be the single biggest way that Americans spend their free time by 2020 – more than watching TV, listening to music, playing video games, or reading.
The amount of time people spend watching TV each day has been pretty steady for a few years now, Mr. Kyncl pointed out, while time spent watching online videos has grown by more than 50 percent each year. Data from media research firm Nielsen shows that it's not just young people watching online videos, either: adults aged 35 to 49 spent 80 percent more time on video sites in 2014 than in 2013, and adults aged 50 to 64 spent 60 percent more time on video sites over the same time period.

Yes, you spotted the main trick to that trick question, different n's :).
And yet, the two quantities are not completely unrelated. As the number of strings grows, the match length also grows. Supposing you have an alphabet of 26 letters, and 27 strings to sort. At least 2 of the strings must start with the same letter. With 26^2+1 strings to sort, that grows to 2 matching letters at the start for at least 2 of the strings.
