In and of itself it really does not. All Taekwondo kata that I am familiar with (though they call them poomsae or hyung) are very similar to Shotokan kata. They are all done solo. Typically, TKD kata have kicks sooner and do not emphasize low stances to the same degree.The closest to that that I have done was in tae kwon do. Yes, I did like it, although I'm not convinced being good at kata has anything at all to do with how well you would do in a serious self defense situation on the streets.
About the only correlation between performing a solo kata and practical use is whether or not you are performing the techniques well. Otherwise, how you handle yourself against an opponent is not really a function of kata. That is handled in kumite, or in the case of taekwondo, kyorugi.
