It's access to the Rosetta frameworks in current versions of Mac OS X that 
makes this possible, and it's the support for Rosetta which is disappearing in 
Lion, and consequently the support for such legacy software. Anything marked 
"Intel" or "Universal" will continue to work in Lion, since those items do not 
require Rosetta.

Rosetta is a technology which creates a link between the Intel processor in 
your modern Mac and the PowerPC code in your older apps, which by themselves 
are incompatible with Intel processors, just as Intel-only apps are 
incompatible with PowerPC processors such the G4 and G5. Universal apps contain 
both Intel code and PowerPC code, allowing them to run in either environment. 
There is no corresponding bridging software which allows an Intel-only app to 
run on a PowerPC processor. 

With the release of Lion, Apple are putting the final nail in the coffin of the 
PowerPC Mac.
