Yes exactly. The boss chorus shifts alternately between a tone that is
slightly high, to one that is slightly low, combined with the input. It is
moving. Detune is created in a different way.

"Chorus is a varying pitch shift. The pitch slowly changes between flat and
sharp. Detune is a constant pitch shift."

"The main difference between the detune effect and the chorus effect is
that the detune amount does not change: the modulating pitch is specified
as an offset to the original pitch."

>From the Digitech RP355 manual :

"A Detuner makes a copy of your incoming signal, takes the copied signal
slightly out of tune from
the original, then mixes the two signals together. The result is a doubling
type of effect as if two
guitars were playing the same part together."

"A Chorus adds a short delay to your signal. The delayed signal is
modulated in and out of tune
and then mixed back with the original signal to create a thicker sound."

So they are created in a different manner, one through pitch only, the
other through moving time delay only.
