cfswitch tag not working the same as cfscript switch

I have been running this code, and it gives different output, and it seems to be a bug. but the ACF also gives the same result

the switch() must evaluate to true or 1 otherwise its pointless. The idea is that the regex will return true or false. In this particular case the regex returns the position which is 1, so true also works

But generally speaking if the regex is written differently the switch statement must react to true value only

if that makes sense.

can you post the source as a trycf gist?
