Yep, I agree. I'll add that UPS's ramp is on the south side of 27L. While 27R is the primary landing runway in a west config, it is not uncommon for UPS to be offered 27L unsolicited.
There were a lot of other items on the recording that could have made the "untrained ear" curious, so I was not sure which got your attention.
