OpenVPN port sharing - can traffic be distinguished from HTTPS?

Question

I intend to set up OpenVPN with the port-share option on port 443.

--port-share

When run in TCP server mode, share the OpenVPN port with another application, such as an HTTPS server.

Can a network node which routers the OpenVPN traffic distinguis it from "regular" HTTPS traffic?

suggests that a sufficiently motivated attacker can distinguish OpenVPN traffic from HTTPS.
