Indeed. Prompted by your report, a spectrum was taken with the 2.3m 
telescope + DBS spectrograph in Siding Spring, which shows a strong 
H-alpha emission with P Cygni profile. Similarly, V5558 Sgr is bright 
again with emission lines switched back to P Cygni profiles. The whole 
behaviour strongly resembles what we found for V4745 Sgr in 2003, i.e. 
rebrightenings as minor outbursts with enhanced mass ejection (Csak et al. 
2005, A&A).
