This grease is a lubricant.
Teflon tape's major role is that of sealant.

Contrary to the belief& *recommendations some:

Now I'm not an expert, but that web site shows the teflon tape all wound
in the wrong direction! *Or are they using reverse threads? *I was

That's correct. Example. Hold pipe in left hand with threads sticking
out to the right. Wrap tape around with right hand rotating over top
to the outside (or 'right').

Wrapped the other way will usually wind up with all the tape pushed
right off the threads.
