Heyho.

I just like you to know that your example unfortunately didn't work for me. I read your tutorial with great excitement and tried it out.

My problem was, that your example didn't change my destination file at all.
I myself wrote something that changed the destination only one time, once a change event triggered. But nothing after that happened.

So I am pretty happy to find this simple solution.
I understand why you want to use runSequence, but this one actually didn't do anything. So I left it out at called the actual function that writes the destination file.

Here are my changes that made a multiple synchronization work for me

gulp.watch './YourPath/**, (file) ->
    browserSync.reload(file.path) if file.type is "changed"
    gulp.start 'src'

#gulp.task 'build', ->
#  runSequence 'clean', ['src']

Btw, I like the clean style. Thanks for the tutorial.
