Network design - switches in a stack over a PTP link

Hi,
I have started work at a new company and come across a network design that is in place.
I have not familiar with this so please let me know if it is normal or not and why.
There are two sites.  Lets call them site A and site B.
The sites are linked together using PTP links at both sites.
Everyone at site B connects back to site A over the PTP Links for internet access.

Earlier today, I connected to a switch virtual stack at site A and noticed there were switches from the site B in this virtual stack.
Shouldn't site A's switches be in their own virtual stack and site B's in their own virtual stack irrespective of the internet link.

What do you mean by "virtual stack"?

I would also be a tremendous help to know what make/model switches you're talking about.

I assume you're talking about clustering? Something like: http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2900-xl-series-switches/4085-61.html

In my opinion that shouldn't be an issue (assuming the PTP link is stable and doesn't give you much down time). I can image that this was set up with easy of management in mind. As long as you have a standby command switch on the other end (command switch is at site A and a standby command switch is at site B), I don't see any problems with this specific setup.

Of course it is a choice of the administrator to determine what works best for him/her and the company (in this case: you).

Yes clustering. But clustering across a WAN seems odd to me.
Your help has saved me hundreds of hours of internet surfing.
