It's all a matter of scope. When you use the TRACE keyword instruction, the scope of that instruction is that executable block of code. If you invoked a method or a routine, this is an external call and the current trace settings are not inherited. Nothing will get traced in those cases because the trace setting in the new block of code reverts to the default of TRACE Normal. When ::options trace was introduced this gave a global setting for the package that defined what the trace setting should be on entry to a new block of code. This made life easier because you didn't have to update each code unit to turn things on. However, it got somewhat confusing because the context would jump around a lot. To address this, an additional trace line was introduced to show what code block was being entered. This would appear with trace all, results, or intermediates. The last enhancement was to also do this for trace labels, which gave a nice flow of control trace for the package.
