Frogspawn Tissue Receding... but coral growing?

[KyRo]

I know tissue recession isn't a good thing, but the coral seems to be growing and doing great. I got a 2 headed frogspawn a couple months ago and while the white tissue on the base has receded a little bit, the coral is much fuller and bigger than since I got it. Is this an issue then? I have had one hammer with tissue recession and it didn't look too good going forward and closed up constantly, but this thing looks great. Anyone have any ideas?

I don't think it should be a issue but you should keep a eye on it just to make sure.
