(tho' the logic of Boolean diadics not returning Boolean values escapes me...)

It allows idioms such as: 

$hostname ||= 'localhost';

[download]

Since that is just short for: 

$hostname= $hostname || 'localhost';

[download]

it'd set $hostname to just 'true' if Boolean operators returned Boolean values. Of course, the above is short-hand for: 

$hostname= 'localhost'  if ! $hostname;

[download]

but the first form is the only one that manages to not repeat $hostname, which can be quite an advantage in some cases, or across a bunch of similar cases. And there are other similar idioms that are useful because of this property.

In any case, it is quite "Perlish".
