The indent for the fold start and fold stop marker needs to be the same.
So, at least now I understand the mechanism; it was not clear for me after reading the manual (sorry). Let me write it down explicitly for reference (correct me if I'm wrong):
Folding is determined by the patterns listed in the language definition. But a startfold and an endfold markers will be coupled only if they have the same indentation, otherwise they will be ignored (well, at least one of them). Thus if I write in a tex file
\begin{equation} \begin{split} \end{split} \end{equation}
line 1 is coupled with line 3 and line 2 is coupled with line 4. Moreover, the couple l2-l4 is nesting level 1, while the couple l1-l3 is nesting level 2
I am more and more convinced that an option to ignore indentation could be useful... at least for languages like LaTeX, where indentation is just a matter of taste. One might add more precise start/stop markers in the language definition to ensure proper coupling
