Question about Mapping DB Recursion Depth on Fiasco.OC

as far as I understand, the mapping database consists of a treemap
with an entry for each superpage. Each entry points to an array
describing the page's mappings (mapping tree). Each element of this
mapping tree either represents a mapping or stores the address of a
treemap, if the superpage has been splitted into pieces with a size of
the next smaller valid page size.
Is it correct that an element of a mapping tree references another
treemap only in case the page has been spllitted and therefor the
maximum recursion depth is limited by the amount of valid page sizes?
