You can do that for virtual machines running on standalone hosts but if you manage these hosts using a single vCenter then the virtual machines should have unique mac address.

that can happen if your host's port group has NIcs connecting to different switches - so when the VM's traffic flows through a switch its mac is learned against the VM's VLAN - I do not think this is going to be an issue - are you observing any issues?

I may have misunderstood your question earlier -- if the switches are completed isolated then it might be possible - otherwise vma -> switcha : vmb:switchb - now vma wants to communicate with a vmc running on switchb at layer2 - then it is possible that the reply from vmc intented to go to vma could go to vmb...
