Yes. Think of it like this:
SIGNAL() declares an ISR that will disable all interrupts.
INTERRUPT() declares an ISR that can be interrupted by other interrupts.

In practically all cases, one should never use INTERRUPT(). It's highly 
dangerous as you can quickly blow your stack depending upon your 
application, number of interrupts, frequency of interrupts, etc.
