No.  Try it.  When you (eventually) close the (say, xterm) session the ssh
client will be killed.  And the sshd on the other side will too.  Or at
least that's what happens here with my 2.9.9p2.  Left is my perl script. 
And data is lost.  But it's not at the fault of OpenSSH, but of me.

You could do that too.  Or just SIGTERM, that works too.
