Agree, PHY data rates and IP throughput are not the same. Even in Wave 2, the requirement for 160MHz wide channels makes >1Gbps (actual) questionable. You will not oversubscribe your 1Gig wired connection with Wave 1 802.11ac devices.

You can't do a direct apples to oranges comparison between wired and wireless bandwidth. Remember, that wired connection is one gig in each direction for an aggregate of two gig of bandwidth, compared with the total half duplex 1.3 (in ideal conditions) on wave 1.

The 802.11ac supports 1.3GB, but the AP only has a 1GB wired connection.
802.11ac with 4x4 multiple-input multiple-output
(MIMO) technology with three spatial streams, offering sustained
1.3-Gbps rates over a greater range for more capacity and reliability
than competing access points.
Interfaces
€ 10/100/1000BASE-T autosensing (RJ-45)
€ Management console port (RJ-45)

They almost got it into a 802.3af power budget, except it runs in 3x3:3
MIMO instead of 4x4:3 which shouldn't make too much of a difference.
