<start_of_turn>model
No, sentences 1 and 2 do not express the same meaning. In sentence 1, Sharon Northe has been the head of the group since 2003, while Heather Weaver became president in 2017. In sentence 2, Heather Weaver has been the head of the group since 2003, and Sharon Northe has been the president since 2017. The positions of "director" and "president" are swapped in sentences, changing the meaning of who has been in charge of each position since when.<end_of_turn><eos>
