[Pool] NIST servers in the pool?

Good evening:

Pardon me if this has already been address, but I noticed something that 
seem odd today while setting up a router for someone.

The site is setup to use the pool for time services using 
0-4.us.pool.ntp.org, along with server at another site (the flaseticker 
below).

When I checked to see if the device had synced its clock, I recognized 
the two IPs pointed out above.   They are NIST servers.

Just curious, but I thought the pool existed to take the load off of the 
Stratum 1 clocks, but here they are included in the zones now.

Is this expected and sanctioned?
