Re: By any other name...
I'd say that is exactly the reason why the masked sound appears to
continue throughout the duration of the masker. The brain has no
evidence to assume the attended sound actually ceased. From the same
philosophical point of view you would have to assume the effect can only
persist for as long as the attended signal is, at least to some degree,
predictable, e.g. on a time scale of phonemes for speech sounds and in
music probably related to meter.
Of course a microphone and some signal processing would most likely be
able to prove that the sound was absent from the acoustic signal.
(Un)fortunately, the brain doesn't have access to the acoustic signal
Coincidentally, the quote from Lewis Carroll in the signature below
appears very appropriate for this discussion (especially if you care to
remain in a philosophical mood for a little longer).

if it were so, it would be; but as it isn't, it ain't. That's logic!"
