Correct.

1 of something worth $2 is the same as 2 of something worth $1.

With all fixed supply models (bitcoin et al) the price is the variable.

With Radix the supply is the variable.  Granted, the attempt isn't to "fix" the price, but to substantially smooth out the high volatility through autonomously generated supply based on the demand. 

Our test scenario where we ran several years of bitcoin txns (over 500M) through the model from day 1 through (I believe) 2015 produced a variance of around 3% +/- from the initial bitcoin value.   

With that decreased level of volatility you don't have to sit around and hope/pray the price doesn't crash, but can go about your day and just login whenever to get the latest dump of back paid interest on your existing holdings.  And if you are running any of the services that provide features for the network like marketplace, chat, mail, distributed exchange, apps...etc then you'll get rewards of new supply as the economy inflates.
