I don't understand last sentence of comment

! /*
! * Ada-based PL/SQL uses := for assignment and variable defaults, while
! * the SQL standard uses equals for these cases and for GET
! * DIAGNOSTICS, so we support both. FOR and OPEN only support :=.
! */
! assign_operator : '='

"FOR and OPEN only support :="

FOR statement nor OPEN statement doesn't use ":="
