Inconsistent hyperlinking of author

In the repo https://bitbucket.org/jglick/ml-hgext, there are some changesets made by the original author:

user: Marcus Lindblom [macke%40yar.nu]

and some by me in a fork:

user: Jesse Glick [jglick%40bitbucket.org]

In the HTML version of this page, my changes are listed as

<td class="author">Jesse Glick</td>whereas Marcus's are listed as

<td class="author">Marcus Lindblom</td>When I am logged in to the site, my name is given as plain text, whereas Marcus's is hyperlinked:

<a style="" href="/marcusl" title="Marcus Lindblom">
marcusl
</a>In https://bitbucket.org/jglick/ml-hgext/changesets also Marcus is hyperlinked while I am not (whether or not I am logged in):

<dd>Jesse Glick </dd> <dd><a href="/marcusl">Marcus Lindblom</a> / <a href="/marcusl">marcusl</a></dd>Why the inconsistency?
