You've missed the operative words, "EFFECTIVE RADIATED ISOTROPIC POWER" 
-- in simple words, the power limit takes antenna efficiency into 
account, and almost any antenna 99.9% of hams can put up for 600M is 
going to be VERY inefficient.. I've seen a suggestion from a good 
engineer  that 100W through a tuner into a typical 160M transmitting 
antenna like an inverted L or Tee vertical, with radials, would get you 
fairly close to 5W ERIP.  So what we're going to be looking for is 
transverters with very good antennas, small power amps, and antenna 
tuners designed for the much lower frequency.
