Hm ... I follow you so far, ikegami ... but why do I get different output in the following two cases:
~$ perl -le 'print $& if "aabbaab" =~ /aa|bb/g'
~$ perl -le 'print join "\n", ( "aabbaab" =~ /aa|bb/g )'
aa
bb
aa
~$ perl -le 'print join "\n", ( "aabbaab" =~ /(.)\1/g )'
a
b
a
The first two system responses are clear ... but why does the last regex using backreferences return only single characters?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
