Source code does not come in "32 bit" and "64 bit" flavours. :)

There are potential issues with poorly written source that is written
assuming a 32 bit architecture that will not work on a 64 bit
architecture, but that isn't "32 bit source", it is simply buggy code.

Many of these 64-bit issues are already fixed in Debian because Debian
has for a long time supported other 64-bit architectures (e.g. Alpha).

But yes, essentially it is as you say.  When you compile for a 64 bit
architecture, you use the same source code that would be used to compile
the app for a 32 bit architecture.
