That doesn't seem to be it either.  For example, on my master, I have:

database    hdb
suffix      "dc=stanford,dc=edu"
rootdn      "cn=manager,dc=stanford,dc=edu"

# Syncrepl Provider
overlay syncprov
syncprov-checkpoint 1000 60

# Dynamic Group Overlay
overlay dyngroup

# Uniqueness Overlay
overlay unique
unique_base cn=people,dc=stanford,dc=edu
unique_attributes suunivid suproxycardnumber sucardnumber suuniqueidentifier

# Valsort Overlay
overlay valsort
valsort-attr suOrgContactStanford cn=orgs,dc=stanford,dc=edu weighted
valsort-attr suOrgContactWorld cn=orgs,dc=stanford,dc=edu weighted
#valsort-attr ou cn=people,dc=stanford,dc=edu weighted
#valsort-attr suAffiliation cn=people,dc=stanford,dc=edu weighted
#valsort-attr suDisplayAffiliation cn=people,dc=stanford,dc=edu weighted

overlay     accesslog
logdb       cn=accesslog
logops      writes
logsuccess  TRUE
logpurge    07+00:00    01+00:00

As you can see, *multiple* overlay statements and directives, prior to the 
"limits" command.  It does not exhibit the problems I see on my replica. 
The issue only arises once dynlist is enabled.
