It depends on the charger. Apple made multiple chargers which would work 
with that model. The lower-end ones simply didn't provide the power 
necessary to run the CPU at max by themselves, they needed battery power 
as well. This meant that, yes, when running at full power, the laptops 
would slowly lose charge even when plugged in. Fortunately this was only 
for peak CPU usage, which was not usually prolonged, so the battery 
would start to charge again when the CPU usage went down. Or the user 
could just get a more powerful charger.

Note that this still happens with some devices. If I use the standard 
iPhone charger with my iPhone 6 while I'm running something CPU 
intensive, such as Civilization 6, the iPhone will lose charge, slowly. 
If I use a more powerful charger, either a 3rd-party charger such as the 
Belkin I normally carry in my laptop bag, or the charger for an iPad, 
this does not happen. The iPad itself has been known to slowly lose 
charge when plugged into the USB port in my car, a Toyota, if I'm 
running intensive apps on it.
