I understand that getting a 4+ in a single row/column grants an extra match chance. Is the "T" match with 5+ gems, a "+" match that is 5+, or a |_ corner of any rotation with 5+ gems meant to give an extra match chance? It seems the programming may only look at an in-line match and not a quantity of the match. I am no programmer, so I cannot help unfortunately, but I hope this will be updated in a version so getting those harder 5+ matches gives a proper reward.

No, it is a design choice, as the number of gems in a match will already give you a stronger result. If they also give an extra action, then the decision would be to almost always go for them. This way, you have to make a decision whether you want an extra action or extra gems.
