Does fastq-dump return interleaved files?

For example,
fastq-dump ERR315863

Here's the head of my file:

(base) -bash-4.1$ head -n 10 ERR315863.fastq

This run is HiSeq 2000 so I'm assuming it's R1/R2 reads but these reads don't look paired:

What did fastq-dump download with this command and not specifying --split-files?
