You mis-understood.

When the ISR is running, can it be re-entered (presumably by another 
interrupt)?

When you use what in main what doesn't change?

Also how is the behaviour different when you use ch1 as opposed to ch[1]?

Right now this sounds more like an issue in main rather than the ISR but 
it's rather difficult to tell.  It could be a heisenbug.
