Hi rujing zha,
The TENTs are kept together, the neighboring bricks go across TENTs. Each set of TENTs will be grouped before those for the next event in IM.
Note that in such a design, it would be bad for the BOLD responses for any events to overlap. This is a dangerous design in any case, since these TENTs might fit single time points (and therefore perfectly), if they are TR-locked events.
