Harrington on Hold'em Clarification

[New York Jet]

On page 58, Dan in discussing Optimal Strategy for Small-Stakes Multi-Table Online Tournaments:

"Push your good hands (top pairs, trips) to the maximum, again with the hope of doubling up. You're much more likely to be called all-in than in a normal tournament. Remember that even your weaker top pair hands, like nines and eights, go up in value while high unpaired cards go down in value."

I find the last sentence a little confusing. Is he saying 99 and 88 go up in value while AQ and AJ go down in value? Or does he mean that post flop A9 with a flop of 952 goes up in value while AQ with a flop of 952 goes down in value?

Thanks in advance,
