Double reboot BrowserSync?

Question

gulp.js

There are two watchers in the Gulp build, one monitors changes in php and html files with a callback to browsersync.reload, the second monitors sass files and a callback for sequential execution of tasks for sass and reload. The php files contain the paths for the compiled styles in the usual way. Now, when I make changes to sass, not only does my sass task work up to three times, then reload, again sass task and reload again. I commented out the watcher for php and html, after that the sass task began to be processed normally ... Can you tell me what caused this behavior of Gulp?
