when both options (-B and -J) are used, bind_interface ( -J ) option is ignored.

Per the ssh_config(5) description for ProxyJump, please set any options that you want applied to the jump host in your ~/.ssh/config file.

Most options on the command-line are intentionally not propagated to the "jump" connection because that would make it impossible to set per-hop policy.

So for your case, instead of "ssh -B em0 -J foo user@bar" you can use a config of:

Host foo
  BindInterface em0

and

ssh -J foo user@bar
