Because the logic of the while construct doesn't require any
connection between the condition and the topic of the body.
In something like this, for instance:
while (!$file.eof)
{
my $line = $file.read();
...
}
Does it really make sense to have $_ set to the return value of
the eof call?

These examples seem to me to make more sense as for loops anyway.
