Hi Atif,
Really good questions.
Before the latest Moodle version, there wasn't possible to do sequencing of activities within Moodle. It was I believe very recently that this was available (I think Moodle 2.3 or 2.4, cannot recall for sure).
Additionally, LAMS provides other features like Branching,
But my reading is that LAMS and Moodle are very different products:
Moodle is a full-fletched learning management system (LMS) with full course features.
Whereas LAMS is a learning platform to create and deploy sequences of learning activities. And not so much course management and all.
In LAMS we focus on the process of learning more than the course management and therefore we provide tools to create learning "workflows".
Yes, LAMS also has courses, subcourses, gradebook, user role controls, etc like a LMS... but that's not really where we put a lot of our emphasis though.
There are a few videos in YouTube that can provide a better overview of LAMS if you want to have a look.
Personally, I think the Moodle and LAMS integration is a real plus to teachers as it brings the best of both systems. Moodle for all their LMS capabilities and LAMS for its ability to create, reuse and run learning sequences with students.
I hope this helps.
Thanks,
Ernie
