Promoters and Protectors are likely to get along famously. It is great fun for the tough, outgoing Promoters (ESTPs), born gamblers and wheeler-dealers, to see if they can win over the reserved and friendly Protectors (ISFJs) and persuade them to let go of their caution and concern for a little while, and take a few risks.
This sounds a bit more like LIE + ESI to me...
Still, he seems to have the types right, even if the description points towards LIE (maybe)

Yeah anyway, I don't know Phaedrus. I know myself that it's far easier for me to attract ISFjs than INFps, irl. Or rather...INFps are harder to keep.
