index time SED from props.conf

Are the SED commands in props.conf excuted in order? In other words

Note: (All the following is under [default])

Can I write a test to set a field so it will fail a SED test

SEDCMD-callid =s/(.*callid)(=)(.*)/\1~\3/g

then run the main SED test

SEDCMD-ssnmask = s/(.*[ :=;,])(?!000)(?!666)(?!9)\d{3}[ -](?!00)\d\d[ -](?!0000)(\d{4}[ =;,&].*)/\1###SSN-SCRUBBED###\2/g
SEDCMD-ssnmask1 = s/(.*[ :=;,])(?!000)(?!666)(?!9)\d{3}(?!00)\d\d(?!0000)(\d{4}[ ;,&=].*)/\1###SSN-SCRUBBED###\2/g

and then change it back

SEDCMD-callid_fix =s/(.*callid)(~)(.*)/\1=\3/g

or might the indexer not always run the SED commands in that order?
