Hi Radim,

In WMS mode, when multiple layers have the same name, they are renamed 
to make them unique (a number is added to the end). If you do a 
GetFeatureInfo you will see the new names.

If you want multiple layers to be turned on using a common name, you 
could use the GROUP setting. That's how we normally handle 
scale-dependent layers for a common theme in WMS mode.
