The difference in the length of the accents, visible in FE between the accent in b. 273 & the 2nd accent in b. 274 and the remaining accents in b. 274-276, does not necessarily mean that they should be diversified. It may be a result of a different origin of these two accents, which were probably added only just in the last stage of proofreading of FE (it is supported by their absence in EE). The latter was inaccurately reproduced in GE1, which was then corrected in GE2 (→GE3).
