I Speak Like a HKer

I found something interesting when I was watching HK news on TV today. A HK offical was being interviewed and I found he liked to spatter English in his Cantonese words, which reminded me so much of my own talking style. Actually I am the guy who loves to disseminate English in Cantonese dialogues. I have no answer about when this habit was formed in the first place and how it developed so quickly. Is this a good habit? Tell me please.
