The accent over the trill in A is clearly shorter than long accents at the beginning and end of this bar. However, long accents in the next bars already do not contrast so expressly with the discussed sign, hence we consider its interpretation as a long accent to be most likely. The missing accent in GE1 (→FE→EE) is certainly an oversight. The sign was added in GE2 (as a short accent).
