Calabash When should P:log be executed?

Hi,

Using p:log for debugging my pipelines I remarked that the existence of 
path is checked before everything else which disallow to create 
subdirectory before the step that is logged is executed.
The attached example in Calabash 1.1.4  show in the first run:
Failed to create log: file: XXXXXX
Is this the correct behaviour?

Sincerely

Pablo Strasser
