Yeah, seems to have the yo-yo effect. They are still forecasting it to track almost due north from its current position, along the ridge of the high.
Meanwhile, i'm liking that low behind it even more than i did yesterday. Of course, it's way too early to say, but it seems to be heading in our general direction. The above map is for 6 days time. If that high holds its form, then it should steer it right into Taiwan.
