What is a tritone in music theory?
A tritone substitution is taking any dominant 7 chord you see and play another dominant 7 chord that occurs a tritone (#4 aka b5) away from that initial chord. For example: playing Db7 over G7. The reason that this substitution works is that dominant 7 chords with a bass note a tritone apart share the same 3rd and 7th.

So, your basic chord progression G7 / C becomes Db7 / C
The tritone chord Db7 is one fret above the target chord C.
Lenny Breau was talking 6 string guitar in that lesson Paul was referring to ( very specifically a V7/I type chord change) and applying it to steel. Both necks, I presume.
I don’t believe he was implying that that is the only way to play this type of change, just the easiest way to think about it. In fact, if the target chord is minor (G7 / Cm), the tritone substitute one fret above target chord concept does not hold true on the E9 neck.
