Actual bona fide

What does Actual bona fide mean in American Law?

The definition of Actual bona fide in the law of the United States, as defined by the lexicographer Arthur Leff in his legal dictionary is:

There seem to be two uses of this locution. The first is just a matter of combining two ideas, e.g., an “actual bona fide possessor” is one who is both one in “actual possession” (as contrasted to, say, constructive possession) and in “bona fide possession” (i.e., in possession in good faith). The second use, however, seems to [be] just for intensification or emphasis. For example, in “actual bona fide purchases,” neither “bona fide” nor “purchaser” is changed from its usual meaning by “actual,”

which thus seems to mean no more than “really.”
