Sync Repositories kinda bug

Hey,

some days ago I used the automatic sync on my fork of "https://bitbucket.org/saibotd/bitbeaker" , now in the Newsfeed of me and other contributors of https://bitbucket.org/saibotd/bitbeaker ,it looks like, they all have committed to my repository, even in the users profiles it gets displayed there.

I dont know if this is by-design or a bug?
