Yes... I presume they meant XIP for multiple programs at once, since you'd need an MMU for that.

Or PIC code... PalmOS 5 & 6 allowed multiple programs in same memory and they were simply compiled pic. MMU was not used
Some architectures (ARM, RISCV, aarch64) are well suited for this kind of code. Others are extremely poorly suited (x86, MIPS), but all CAN do it
