Update: I added an example for an if() conditional, which was the original poster's actual intent.

I think that his implication was just a clarification of a subtlety that escapes many Perl novices.

The point is that you don't have to use the my() declaration between curly braces to define its scope within a block of code. You can use my() within the condition of an if/else block: 

if ( (my $name = GetName()) =~ /^\w+$/) ) {
  print $name;
}

And the variable $name has the scope of that conditional.

You can also use the my() declaration in a loop control statement: 

while (my $line = <>) {
  print $line;
}

foreach my $name (@people) {
  print $name;
}

And the variable's scope is that of the loop. It was certainly a revelation for me, once upon a time...
