It's just a relic of older IOS's that didn't support more than 5 vtys.  So
you config would still work on these older versions as the first vty 0 4
would go through and 'vty 5 10' stanza would error out.  If it was just vty
'0 10' then no line configs would be passed down and possibly preventing you
from successfuling logging in leading to possible downtime to do a password
recovery or to roll a tech.

Does it matter to you?  No.  You can refer to it as vty 0 <max number here>
and be just fine when configuring your lines.  Just the config will display
in the Lowest Common Denominator and still split them up.

Not sure why so many people get hung up on this point.
