Yes, you did go wrong there. The bleach/blix acts as a stop bath, arresting development. Your warm water rinse allows development to continue, effectively increasing the dev time. This technique is mentioned in (historic) books of B&W processing, where contrast control was required.
The technicians who devise processes such as C-41 are highly qualified and they have the huge facilities of research laboratories at their disposal, so they can be expected to get it right. Best to follow their advice, so go straight from developer to bleach/blix. The rinse step doesn't extend the life of the bleach/blix.
