Why not? ord('_') is 95, which is between ord('A') = 65 and ord('z'),
which is 122. OTOH, it is not between ord('A') = 65 and ord('Z') = 90 OR
ord('a') = 97 and ord('z') = 122.
the first regexp matches anything in the set
{a} union {Z} union {everything between A and z}
while the second matches anything in the set
{everything between a and z} union {everything between A and Z}
