You are replacing while a memory variable is either T or F. So, if the memvar is .F., nothing happens. Nothing in the REPLACE is changing the value of the memvar unless you have some UDF in the command. The use of FOR and WHILE in a REPLACE does work,, it is just usually used with a logical test of some field in the record set.
