Multiple server blocks using spdy, reuseport, deferred (no replies)

If we have multiple server blocks binding on https using SPDY, reuseport, and deferred nginx fails to start complaining about port already bound:

server {
listen 443 deferred ssl spdy reuseport;
server_name app.foo.com;
...
}

server {
listen 443 deferred ssl spdy reuseport;
server_name frontend.bar.com;
...
}

What is the behavior then if we change to:

server {
listen 443 deferred ssl spdy reuseport;
server_name app.foo.com;
...
}

server {
listen 443 ssl;
server_name frontend.bar.com;
...
}

Will both server blocks use SPDY, reuseport, and deferred, or only the first?
