It was possible since Simens Step 5 (since late 70s) to change your view between FBD/LAD and AWL. But AWL is just like Assembler, so .. yes. In old machines (we still have about 20 machines with Siemens S5) sometimes it's a must to use AWL.

Translate an IF statement you need to add jumps, so it's not really the same code.
Also for ex. the very simple Siemens LOGO controller has a simple software to program it. But if you use FBD, it's just possible to use a tag once. So if you need a tag multiple times, so you have to draw lines from the single tag. Even for super simple stuff it get's messy super quick.
