You lie! He implied a shell behavior that violated the semantics
specified in POSIX, particularly, that a command line of the form
"binaryname arguments" launches a new, previously nonexisting process
running the named binary, when he implied that a command line with a
particular binary name at the start would fail to do so. The only
command lines that should fail to start a new process are shell
builtins. And of course "screen" is not a shell builtin, it's a
binary's name instead.

Now - I know you are not a programmer, so I will have to explain it
explain it very carefully.

When screen is started the second time the screen binary is started.

After it is started it detects the other instance and connects you to
that and exits.

That is completely POSIX compliant. POSIX does not restrict what
code logic can be but in programs.
