> trying to keep the older models they already have alive
It's not a bad move - if you can maximize the return on DisplayPort monitors, USB keyboards, HDMI cables and MagSafe chargers, it makes sense. Keep in mind the company will eventually have to move to USB-C, as the MacBook Air is the only remaining MagSafe laptop and I won't bet on its longevity. OTOH, the old-style MBPs are enough for most uses, as are the Air for anyone who can live within 8GB.

Not necessarily. A minority of machines are Macs, and I wouldn't be surprised if not wanting to deal with the whole USB-C thing right now is yet another incentive for IT to be interested in ditching Apple.
