Hi
Your example is AND'ing the results of the two matches, so will return true
if both matches occur.
An example of comparing characters using the bitwise AND and the result
might help, or confuse you more thoroughly :)

my $a = "a";
my $A = "A";
my $B = "B";
foreach ($A,$B,$a) {
my $bittest = ($A & $_);
my $logicaltest = ($A && $_);
print "Comparing ",$A," with ", $_,"\n";
printf("Bitwise\nResult is %s\tHex value %x\n\n",$bittest, ord
$bittest);
printf("Logical\nResult is %s\tHex value %x\n",$logicaltest, ord
$logicaltest);
print"\n";
};
OUTPUT
Comparing A with A
Bitwise
Result is A Hex value 41
Logical
Result is A Hex value 41
Comparing A with B
Bitwise
Result is @ Hex value 40
Logical
Result is B Hex value 42
Comparing A with a
Bitwise
Result is A Hex value 41
Logical
Result is a Hex value 61
