I've spent some time to test, so it looks like systemd tries to create the mount point inside the container even if directory exists:
[pid 5519] open("/mnt/data/srv2/root/etc/machine-id", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 5519] stat("/mnt/portage", {st_mode=S_IFDIR|0755, st_size=180, ...}) = 0
[pid 5519] stat("/mnt/data/srv2/root/mnt/portage", {st_mode=S_IFDIR|0755, st_size=70, ...}) = 0
[pid 5519] mkdir("/mnt/data/srv2/root/mnt/portage", 0755) = -1 EEXIST (File exists)
[pid 5519] writev(2, [{"Failed to create mount point /mn"..., 73}, {"\n", 1}], 2) = 74
[pid 5519] exit_group(1) = ?
[pid 5518] <... poll resumed> ) = 1 ([{fd=8, revents=POLLHUP}])
[pid 5519] +++ exited with 1 +++

Starting with systemd 217 systemd-nspawn fails with error code 1 if --bind option specified. The version 216 works fine. The command "systemd-nspawn --bind /mnt/portage -D /mnt/data/srv2 /bin/bash" returns: Press ^] three times within 1s to kill container. Container srv2 failed with error code 1. Without "--bind" the same command workd fine.
