SSH consists of three different protocols (see RFC 4251):

  • The Transport Layer Protocol,
  • The User Authentication Protocol,
  • The Connection Protocol.

If you want to use the OSI model, then the different protocols operate at different layers, somewhere between layer 4 and layer 7.

So, the following quote you've asked about isn't wrong, just a bit imprecise.

IPSec works at Layer 3 of the OSI model, while SSH functions at Layers 4 and 5.
