yes, as even 54326789012345123 contains at least one of the above
patterns.. (actually several possible matches, 10 to be exact, but one
is sufficient for the acl to be true and regex is satisfied when finding
the first match "54326789")

Because the question was about requests larger than 2 MB (approximately
2000000 bytes), so the acl need to match

  2XXXXXX
  3XXXXXX
  ...
  9XXXXXX
 1XXXXXXX
 2XXXXXXX
 ....

but not
  1XXXXXX

as that is below 2 MB.

The first regex matches anything from 10000000 (10 MB) and up.

The second regex takes care of the range 2000000 - 9999999 (2MB to
10MB)

Side note: the second regex also matches many larger values also matched
by the first, but not all. For example it matches 4000000000, but not
10000000. But all these is taken care of with the first regex and does
not matter.
