[j-nsp] EVPN and DPC line cards: Deciphering JUNOS docs?

I am trying to wrap my head around the following note in this doc:
"Note: Prior to Junos OS Release 15.1, the EVPN functionaliy support on MX
Series Routers was limited to routers using MPC and MIC interfaces only.
However, starting with Junos OS Release 15.1, MX Series Routers using DPCs
can be leveraged to provide EVPN support on the CE device-facing
The DPC support for EVPN is provided with the following considerations:
DPCs provide support for EVPN in the active-standby mode of operation
including support for the following:
a. EVPN instance (EVI)
b. Virtual switch (VS)
c. Integrated routing and bridging (IRB) interfaces
DPCs intended for providing the EVPN active-standby support should be the
CE device-facing line card. The PE device interfaces in the EVPN domain
should use only MPC and MIC interfaces."
At first, I assume that this means that EVPN is supported as of 15.1 for
DPC line cards, in PE routers that are facing CE devices. Something that
is a "CE device-facing line card" would be on a PE router. But then that
last sentence confuses me by saying talking about "PE device interfaces"
do NOT support the DPC line cards.
Does anyone have their JUNOS documentation decoder ring handy to try to
help interpret this for me?
