Leap exercise, vectorisation

Programming R
1

Do we have a full understanding if in case of vectorized leap function in R short-circuit operations work as well?
I suspect that only && and || work in short-circuit but & and | do not - how is it?

I made a test, please try it out and reason with me if I am correct:

paused_TRUE <- function() {
  Sys.sleep(2)
  TRUE
}
c(TRUE, TRUE, TRUE) | c(FALSE, FALSE, paused_TRUE())
TRUE || paused_TRUE()
TRUE | paused_TRUE()
c(FALSE, FALSE, FALSE) & c(TRUE, FALSE, paused_TRUE())
FALSE && paused_TRUE()
FALSE & paused_TRUE()

Observe how vectorised version pause execution and simple ones do not, making short circuit. I think if we advise vectorised version in R for leap exercise we cannot talk about short circuiting at the same time. So some changes needed in mentoring guide.
WDYT?
