[arm-allstar] Echolink Question with Psuedo node

[W2YMM]

Hello,I've been running Echolink on my Allstar node on the Psuedo 2nd node
#1999.
First node is 28183 is using Simple usb, Psuedo is 1999. (Same Pi)
My echolink.conf file is set to astnode=1999.
I noticed that if I enter an Echolink node number FROM 28183 it makes an
outbound Echolink  connection.   Inbound Connections to my Echolink W2YMM-L
appear to connect correctly TO 1999.
I never noticed that it could work that way, I thought it was separate.
Does this sound correct ?  Any input would be helpful.   Thanks.
