RELEASE in store.log

From what I have understood in the FAQ and in the user's manual, the
RELEASE tag in the store.log means that a file has been removed from the
cache. (SWAPOUT means that a file has been written in the cache, and
SWAPIN a file has been read from the chache, and has been put in the
memory). If this is true, then how is it possible for a file to be
removed (RELEASE) twice, without being written on the cache (SWAPOUT)
between the two RELEASE?
(here's what I've done to see this :

(The URL used is certainly not the only one in that case)
Another question, if possible : why isn't there more elapsed time
between the date of a file removal (RELEASE) and the date when the same
file is written again (SWAPOUT) in the cache? (see the last two lines in
the exemple)
I hope you can help me. Thank you
