The DEFSYSTEM transforms :DEPENDS-ON into :IN-ORDER-TO and :DO-FIRST
dependencies; :DEPENDS-ON is just syntax.  Perhaps this will help:

CL-USER> (asdf:defsystem sys
	   :components ((:file "f1") (:file "f2" :depends-on ("f1"))))
#<ASDF:SYSTEM "sys" {50DAF1F1}>
CL-USER> (describe (second (asdf:module-components (asdf:find-system "sys"))))
#<ASDF:CL-SOURCE-FILE "f2" {50EC6EA9}>
is an instance of class #<STANDARD-CLASS ASDF:CL-SOURCE-FILE>.
The following slots have :INSTANCE allocation:
 NAME                 "f2"
 VERSION              #<unbound slot>
 IN-ORDER-TO          ((ASDF:LOAD-OP (ASDF:LOAD-OP "f1"))
                       (ASDF:COMPILE-OP (ASDF:COMPILE-OP "f1")))
 DO-FIRST             ((ASDF:COMPILE-OP (ASDF:LOAD-OP "f1")))
 INLINE-METHODS       NIL
 PARENT               #<ASDF:SYSTEM "sys" {50DAF1F1}>
 RELATIVE-PATHNAME    NIL
 OPERATION-TIMES      #<HASH-TABLE :TEST EQL :COUNT 0 {50EC70E9}>
 PROPERTIES           NIL
; No value
