Yes I find that too, unfortunately Im not certain if I'd have taken this sign. The main reason is Im not quite comfortable with this however. I haven't demo'd or papertraded this whatsoever, less just went live by it.
But to answer your question I believe I'd have waited to get the 1M to provide a short sign then on the subsequent long sign I'd have re-enterd.
Once I look at my charts about the 1M it shows 2 longs in a row,
one at 4776 then a second long about 25 minutes after at 4789, without a short sign between them.
