The ARM has a fairly complete description. Does it answer your questions?
ftp://ftp.isc.org/isc/bind9/9.9.6-P1/doc/arm/Bv9ARM.ch06.html#max-recursion-depth
max-recursion-depth Sets the maximum number of levels of recursion that
are permitted at any one time while servicing a recursive query. Resolving
a name may require looking up a name server address, which in turn
requires resolving another name, etc; if the number of indirections
exceeds this value, the recursive query is terminated and returns
SERVFAIL. The default is 7.
max-recursion-queries Sets the maximum number of iterative queries that
may be sent while servicing a recursive query. If more queries are sent,
the recursive query is terminated and returns SERVFAIL. The default is 50.

Per query.
