I saw that wording too and assumed what I think that you assumed. I

those words are to be interpreted. They are to be interpreted as "if
the new length of the file can be successfully set, then the
mtime/ctime should be changed".

What's the basis for that interpretation? The language seems extremely
clear:

"On successful completion, if the file size is changed, these
functions will mark for update the st_ctime and st_mtime fields
of the file, and if the file is a regular file, the S_ISUID and
S_ISGID bits of the file mode may be cleared."

Why are you concerned about this? Do you have an actual application
that breaks?
