I think the thing which tends to confuse me about the wording
is that it's phrased in terms of "releases", ie point events,
(which is OK for users) but the developers who are adding
deprecation notices and then removing features probably think
more in terms of "release cycles" (ie the periods of time between
the point events), or at least I do, so I have to mentally convert
"functional for two releases" into "so if I deprecate it in this
cycle, then I have to leave the code present in the next cycle
and then am OK to delete the code the cycle after that".
But I don't have any good suggestions for wording, and your proposed
text is definitely clearer I think.
