The mark in this bar is a continuation of the 
hairpin (long accent) from the preceding bar, which falls at the end of the page in FE (→EE). EE feature here a short accent, like in the preceding bar. In the main text we give the version of GE, which do not contain any mark in this bar (after the long accent in b. 98).
