This can be easily seen by using <body data-instant-intensity="1000"> - when hovering over multiple links, despite having un-hovered them, they are still preloaded after one second.
Potential solution
Instead of using a variable which only stores one timeout ID at a time, the script should use an Object/a Map to keep track of the URLs having a timeout, and the timeout ID for clearing it.

To me, https://instant.page/intensity#:~:text=Adjusting%20the%20delay%20on%20hover isn't really clear what exactly adjusting the value does.
I'd assume that if a user hovers over a link, but un-hovers within the specified time in milliseconds, nothing would get preloaded.
However, this isn't the case when hovering over multiple links within a short time, or re-hovering over the same link again.
instant.page/instantpage.js

causes the variable to be overwritten while it may still be needed for a different link.
Because the timeout ID was overwritten, clearing it has no effect if more than one link has been hovered over within the configured time:
