Only 1 of those utilizes a TAA (the 3rd, which also goes down to Cat 1 Precision Minimums), which is why I'd expect to see the solid lines there. The TAA is supposed to be a more standardized GPS approach procedure that when combined with WAAS has the capability for Cat 1 mins. Otherwise, I'd expect it's just a scale issue with multiple IAFs? Interested to see what anyone else has to say. I know I can drump up multiple examples of the same (approaches with multiple IAFs that are not connected with a solid line).
Point is, that while there are two of those above approaches with a "T", only one of those two is a TAA "T". The non-TAA one is most likely an older approach, possibly upgraded with LPV minimums recently.
