In SFT and considering moduli of curves asymptotic to Reeb orbits at punctures, They fix markers both on Reeb orbit and at the puncture. Does any body clearly understand why they do that ? What is that for ? Why is that needed?

In Symplectic field theory ( Hofer-Eliashberg....) and considering moduli of J-holomorphic curves asymptotic to Reeb orbits at punctures (J-holomorphic curve into a symplectic cobordism), The authors and every body else who works on SFT, fix markers both on Reeb orbit and at the puncture. Does any body clearly understand why they do that ? What is that for ? Why is that needed?
