for sure you will find code from rehlds code in amxx code as changes made to one of them are made they will be most likely done to the other as well. That's nothing unnormal or really surprising.
But as long as each plugin posted here has to run on hlds and amxx there is no real support for rehlds or reamxx.
Once there is a section for rehlds or reamxx you can say there is.
