That makes a lot of sense, and is supported by the text itself through implication:

When C'baoth destroys the ysalamiri on Wayland, Luke is still able to 'sense' their deaths just before the Force actually returns.

Also, the predatory vornskrs are said to have an instinctual ability to use the Force for hunting, and all of them immediately attack Luke, even on Myrkr where the Force supposedly doesn't exist at all. But all that's really going on is that Luke is blocked from perceiving it, while the vornskrs themselves remain unimpeded--aside from being unable to detect the ysalamiri themselves, whose ability evolved as a natural defence or camoflage. Since a Jedi's connection to the Force would be much stronger than any animal, the effect on them is correspondingly greater.
