hi there, I'm trying to understand the "if" statement used in a loop. what is the different between this two codes? 

foreach my $hash ( keys %some ) {
 if ( $#{ $some{$hash} } >= 1 ) {
  print $#{ $some{$hash} } . "\n";
 }
}

the second code. 

foreach my $hash ( keys %some ) {
 next if ( $#{ $some{$hash} } >= 1 );
 print $#{ $some{$hash} } . "\n";
}

the first code I get printed the length of the array %some, if it contained 2 element or more. but the second code I get print, if it contain 3 element or more. why is those if-statement not the same output?
