typo/my flawed thinking on "alchVdwLambdaEnd"?

Dear NAMD FEP experts,

I haven't found this question in the thread:

In the latest NAMD manual 2.9, I read the section about
"alchVdwLambdaEnd" and compare whatever is stated to the figure (the one
titled "decoupling"&"mutation").

Everything makes sense, until I read the last sentence:
"For lambda values greater than or equal to (1 - alchVdwLambdaEnd), vdW
interactions of the annihilated particle are fully decoupled from the
simulation."
however, in the "mutation" panel, I see that vDW is >0 for lambda with
1>lambda>(1 - alchVdwLambdaEnd) (i.e. for "lambda^{down}_{LJ}")

Is this a typo?, i.e. should it say "linearly decoupled" instead of
"fully decoupled"? If no, is there a flaw in my thinking, based on what
I wrote above?

Many thanks for your help,
Best,
Sebastian
