Silverstripe if else loop

<div class="related">
<% if $RelatedOne.Title != null %>

<a href="$Link" class="play">
    <div class="clip" style="background-image:url('$RelatedOne.VideoImage.CroppedImage(215,120).URL')">
        <img src="$RelatedOne.VideoImage.CroppedImage(215,120).URL" alt="$RelatedOne.Title">
    </div>
    <span class="overlay">
        <span class="title vertical-align">$RelatedOne.Title</span>
        <span class="play-button"><i class="fa fa-play"></i></span>
    </span>
</a>


<% else %>
    <% include RelatedVideos %>
<% end_if %>    

When the title is there the if condition is working properly but for others the else section is not working.Could anyone please point out my mistake.
