Gulp does not work when returning a stream

Question

The following Gulp setup does not work:

var templateCache = require("gulp-angular-templatecache");
var less = require("gulp-less");

gulp.task("angular-templates", function(){
      return gulp.src(TEMPLATES_SOURCES)
        .pipe(templateCache(TEMPLATES_JS, {module: "moonwalk", root: TEMPLATES_ROOT}))
        .pipe(gulp.dest("Temp/"));
});

gulp.task("less-compile",function(){
      return gulp.src("**/*.less")
        .pipe(less())
        .pipe(gulp.dest("./"));
});

gulp.task("release-assets", ["angular-templates", "less-compile"], function() {

    return gulp.src("./Content/**/*.cshtml")
        .pipe(gulp.dest("Dist/"));
});

When I run gulp release-assets, the output is as follows:

[01:24:06] Starting 'angular-templates'...
[01:24:06] Starting 'less-compile'...
[01:24:06] Finished 'angular-templates' after 605 ms

... not good...

However, if I changed the second task, deleting it returnas follows:

gulp.task("less-compile",function(){
       gulp.src("**/*.less")
        .pipe(less())
        .pipe(gulp.dest("./"));
});

Then the setup works !? The output is gulp release-assetsthen as follows:

[01:21:54] Starting 'angular-templates'...
[01:21:54] Starting 'less-compile'...
[01:21:54] Finished 'less-compile' after 2.89 ms
[01:21:54] Finished 'angular-templates' after 741 ms
[01:21:54] Starting 'release-assets'...
[01:22:03] Finished 'release-assets' after 8.9 s

I do not understand this problem. I thought for the stream that is provided gulp.src()?

is necessary return

Can someone explain why this setting does not work if I go back to gulp.src()?

, , ; return , gulp; gulp -less, .

, , , glob, **/*.less, , ; glob node_modules, . gulp.src , glob .

glob - ./lib/styles/**/*.less - , glob , . gulp :

gulp.task("less-compile", function () {
    return gulp.src("./lib/styles/**/*.less")
        .pipe(less())
        .pipe(gulp.dest("./dist/css"));
});
