Yes. There is no real data on disk outside the one written after you cleared the existing data.
As I wrote the size reported by ls is irrelevant except for processes reading the files. You cat command is precisely an example of process reading the log file.

With the redirection, you have transformed the logs to sparse files. The file system layer is "inventing" ephemerous null data on the fly for the missing part and displaying this null data is what is taking time. There is no disk space issue. If you are interested in reading the new logs, you can simply run tail -f on the log file.
