It's a special case and I don't think it is a problem in practice. It only happens when there is a block longer than $subStrSize (the minimum match quanta) with a repeated pattern. Test strings and results are shown below:
>string1
01010101010ddddddddddd01234566789a12345yy
>string2
0123456789b12345eeeeeeeeeeeex01010101010x
>string3
0123456789c12345ffffffffffff01010101010zz
000:001 L[ 11] ( 0 29)
000:002 L[ 11] ( 0 28)
001:002 L[ 10] ( 0 0)
Completed in 0.002126
Best match: >string1 - >string2. 11 characters starting at 0 and 29.
Best match: >string1 - >string3. 11 characters starting at 0 and 28.
Perl is Huffman encoded by design.

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).
