No, not true!
I assume you are possibly confused by the difference between the IPA
oe ligature œ and the IPA small caps oe ligature ɶ.
Starting from the top...
IPA, CXS, X-SAMPA [i] is the high/close front unrounded vowel.
IPA, CXS, X-SAMPA [y] is the rounded form of [i]; the high/close front
rounded vowel. It is found in Fr. "tu".
IPA, CXS, X-SAMPA [e] is the mid-high/mid-close front unrounded vowel.
IPA [ø] = CXS, X-SAMPA [2] is the rounded form of [e]; the
mid-high/mid-close front rounded vowel. It is found in Fr. "deux".
IPA [ɛ] = CXS, X-SAMPA [E] is the mid-low/mid-open front unrouned vowel.
IPA [œ] = CXS, X-SAMPA [9] is the rounded form of [ɛ]/[E]; the
mid-low/mid-open front unrounded vowel. It is found in Fr. "neuf".
Compared to X-SAMPA, CXS makes no change to this vowel!
IPA [æ] = CXS [&] = X-SAMPA [{] (I'm informed). It is a near-open
front unrounded vowel. CXS and X-SAMPA differ here.
IPA, CXS, X-SAMPA [a] is the open front unrounded vowel. In practice,
it is frequently used for the open central unrounded vowel (with the
IPAssociation's sanction).
IPA [ɶ] = CXS [&\] = X-SAMPA [&] is the rounded form of [a], the open
front rounded vowel. It is quite rare in the world's languages & in
conlangs, so some people (like Peter) are content to simply switch &
and {, but I still think using brackets as letters is obtuse, and so
when I used the phoneme in Føtisk, I used [&\], which makes good sense
IMHO (I also dislike being gratuitously incompatible). I've never seen
this vowel used for a low central rounded vowel; I'd probably expect
[Q] to be used instead (then, I can't say I've ever looked!). CXS and
X-SAMPA (obviously) differ here.
There's obviously also IPA [ʉ] = CXS [u\] = X-SAMPA [}]. I actually
sometimes use [0] (zero) for this, because that's the TIPA (IPA
package for TeX) way of entering the vowel, and also because when
Scroll Lock's on, the character that normally enters 0 on my kebyoard
enters ʉ, but I'd consider this wrong for CXS purposes, given that CXS
has also changed [1]->[i\].
