No. In a scalar context it reads the following line. Lines
after that one are *not* read and are available for
subsequent reading. That's why it can be used in a loop.
If it read everything the first time, there would be no
second time.

The reason this reads the last line is because it reads
every line. There's nothing special about the last line
except that it's part of "all the rest". The thing that
tripped this behavior is list context.
This is in _list_ context.

The original code was in _scalar_ context.
