Odd OPN coincidence concerning restrictions

Found here.
Quote:
 The largest three [primes] must be at least 10000019, 10007, and 101.
These 3 numbers, especially the first 2, seem to be inordinately close to 10^x where x is a whole number. If this is a coincidence, I consider it to be a very peculiar one.

With greater computing resources, these limits could undoubtedly be pushed higher, but it was decided to stop at a power of 10 in each case.

I didn't realize it was intentional. Sorry for cluttering the boards.
